Determine the volume of oxygen spent on the combustion of sulfur, weighing 6.4 g.
| January 9, 2021 | education
1. We write down the reaction equation for the combustion of sulfur:
S + O2 = SO2;
2.Calculate the chemical amount of sulfur:
n (S) = m (S): M (S) = 6.4: 32 = 0.2 mol;
3. find the amount of oxygen:
n (O2) = n (S) = 0.2 mol;
4.determine the volume of oxygen consumed:
V (O2) = n (O2) * Vm = 0.2 * 22.4 = 4.48 dm3.
Answer: 4.48 dm3.
