1. 52 litre equals to how many milliliters?52 litre=???? milliliter
Jawaban :
52.000.000.000mililiters
Penjelasan dengan langkah-langkah:
1 liter = 1 × 1.000.000.000
52 liters = 52 × 1.000.000.000 = 52.000.000.000 mililiters
So, 52 liters equals to 52.000.000.000 mililiters
Penjelasan dengan langkah-langkah:
1 liter = 1.000 mililiters
So that :
52 liters = 52 × 1.000 = 52.000 mililiters
2. a truck travels 0.72 km on 0.01 litre of fuel how many kilomatetres will it travel on 1 litre of fuel?
Soal ini dapat dikerjakan dengan cara perbandingan senilai
0,72 km → 0,01 L
x km → 1 L
.
[tex] \frac{0,72}{x} [/tex] = [tex] \frac{0,01}{1} [/tex]
0,72 = x . 0,01
[tex] \frac{0,72}{0,01} [/tex] = x
72 = x
Maka, jarak yg dapat ditempuh dengan 1 L bensin adalah 72 km

5. A compound of nitrogen and oxygen has the formula NO. In this compund there are 8/7 g of oxygen for each 1 g of nitrogen. A different compound has the formula N2O. How many grams of oxygen would combined with each 1 g of nitrogen in N20? a. 4/7 g b. 1 g c. 8/7 g d. 2/7 g e. 16/7 g
Matter : Stoichiometry
Sub matter : Dalton's Law
Weigh of O = 8/7 gram of N
Ratio mass of NO:
N ÷ O = 7 ÷ 8
Compound N2O:
2×N ÷ O = 7 ÷ 8
2 ÷ O = 7 ÷ 8
O = 16/7
Answer is E.

6. A van left Singapore at 11.20 o.m. for a city in Malaysia travelling at an average speed of 90 km/h. It arrived at the destination at 1.50 p.m. (a) How far wos the city from Singapore? (b) If the van travelled 18 km on 1 litre of petrol, how much was the petrol bill at $1.95 per litre? Give your answer to the nearest cent.
13.50 pm - 11.20 am = 2 hour and 30 minutes (the total time the journey took)
A. 2 1/2 x 90 = 225 km
B. 225 km : 18 km = 12,5 litre of petrol
12,5 x $1.95 = $24.375 (24 dollar and 37.5 cent

11. how does breathing out 16% of oxygen make CPR effective
Ketika kita menghirup oksigen tidak semua oksigen mencapai alveoli dan ditukar dengan karbondioksida. Ada oksigen yang baru mencapai trakea atau paru-paru tapi tidak mencapai alveoli yang tetap kita hembuskan. CPR adalah teknik keselamatan yang digunakan pada orang yang detak jantungnya berhenti atau kesulitan bernapas. Dengan adanya 16% oksigen yang kita hembuskan, berarti kita bisa memberikan oksigen itu melalui CPR dengan pernapasan mulut ke mulut. 16% oksigen ini yang akan menolong jantung dan paru-paru tetap bekerja.
12. How many grams in 5,6 liter of water in stp ? (Ar. H=1 O=16)
Penjelasan:
n=mol
Water=H2O
V=Vstp × n
5,6=22,4 × n
n=0,25 mol
n=mass/Mr
0,25=mass/18
mass=4,5 grams
13. how many litres of cola are there in 6 similar cans if each can contains 0 .33 L of cola ? round off your answer to the nearest litre

6 cans contain = 6 x 0,33 L
= 1,98 Litre
≈ 2 Litre (rounded to zero decimal place)
14. 2.A litre of mixture consists of 0.25 litre of coconut water, 3/5 litre of plain water and the rest is honey. What is the percentage of honey in the mixture?pakai cara ya jawabnya,yg salah di report,jangan asal jawab ya
Jawab:
0,15 litre
Penjelasan dengan langkah-langkah:
A litre of mixture consists of 0.25 litre of coconut water, 3/5 litre of plain water and the rest is honey. What is the percentage of honey in the mixture?
The percentage of honey can be counted by
1 litre - 0,25 litre of coconut water - 3/5 litre of plain water
= 1 - 0,25 - 0,6
= 0,15
So the honey is 0,15 litre.

17. A Coumpound of nitrogen and oxygen has the formula NO. in this compound there are 1.143 b of oxygen for each 1.00g of nitrogen.A difreng compound of nitrogen and oxygen has the formula NO2. How many grams of oxygen would be combined with each 1.00g of nitrogen in NO2? a. 2.286g O b. 1.000g O c. 0.5715g O d. 4.572g O e. 2.000g O Mohon bantu dengan Caranya ;)
N2+2O2→2NO2
perbandingan mol N2 dan O2 adalah 1:2
1gram N2= 1:28 mol= 0.0357142857 mol,,,
jadi mol O2 = 0.0714285714 mol
jadi massa O2= 0.0714285714 x 32 = 2.2857142848gram
A

19. Luke had a 2-litre carton of apple juice. He drank 1 4 ℓ of the apple juice. How many litres of apple juice were there left? Jangan ngasal ya terima kasih (kalo gak ngerti pake kamus)
Jawaban:
[tex] \frac{3}{2} \: l[/tex]
Penjelasan dengan langkah-langkah:
Tl : Luke punya 2 liter jus apel, dia kemudian meminum ¼ liter. Berapa liter jus apel yang tersisa?
Jus yang diminum :
= 2 × ¼
= ½
Jus yang tersisa
= 2 - ½
[tex] = \frac{4}{2} - \frac{1}{2} [/tex]
[tex] = \frac{3}{2} \: l[/tex]
20. Berapa gram oksigen yang diperlukan untuk dapat bereaksi sempurna dengan 27 g Al?(27 g of Al will react completely with how many grams of oxygen?)
Jawaban:
The balanced chemical equation is as follows:
4Al+3O
2
→2Al
2
O
3
.
Here, 4 moles (4×27g) of aluminum reacts with 3 moles (3×32g) of oxygen.
Thus, the weight of oxygen required to completely react with 27 g of aluminum is (3×32g)×
(4×27g)
(27g)
=24 gm
