How many molecules does 1120 liters contain? hydrogen sulfide?
| February 4, 2021 | education
Given:
V (H2S) = 1120 l
Vm = 22.4 l / mol
NA = 6.02 * 10 ^ 23 mol − 1
To find:
N (H2S) -?
Decision:
1) Calculate the amount of hydrogen sulfide substance:
n (H2S) = V (H2S) / Vm = 1120 / 22.4 = 50 mol;
2) It is necessary to calculate the number of hydrogen sulfide molecules:
N (H2S) = n (H2S) * NA = 50 * 6.02 * 10 ^ 23 = 3.01 * 10 ^ 25.
Answer: The number of hydrogen sulfide molecules is 3.01 * 10 ^ 25.
