The volume that 50.2 grams of CO2 gas will occupy at stp is determined as 25.54 dm³.
Number of moles of CO2 gas
The number of moles of 50.2 g of CO2 gas is calculated as follows;
n = m/M
where;
- M is the molar mass of CO2 = 44
- m is the reacting mass
n = 50.2/44
n = 1.14
Volume occupied by the gas
At stp 1 mole of an ideal gas occupies 22.4 dm³
1.14 = ?
= 1.14 x 22.4
= 25.54 dm³
Thus, the volume that 50.2 grams of CO2 gas will occupy at stp is determined as 25.54 dm³.
