Answer:
The volume of carbon dioxide produced is 14L
Explanation:
Step 1: Data given
Mass of carbon = 7.5 grams
Molar mass of Carbon = 12 g/mol
STP = 1 mole of any gas occupies 22.4 liters
This means 12 grams of carbon occupies 22.4 liters
Step 2: The equation
C + O2 → CO2
For 1 mole Carbon consumed, we need 1 mole oxygen to produce 1 mole CO2. This is a 1:1 mol ratio.
7.5 grams of carbon will occupy (7.5/12)*22.4L = 14 liters
7.5 g of carbon is burned completely, 14 liters of carbon dioxide are released.
This is because at STP, 1 mole of any gas occupies 22.4 liters of volume and 7.5 grams of carbon is 0.6 mole of carbon. Since carbon produces carbon dioxide in a 1:1 ratio when burned, it means that 0.6 mole of carbon dioxide will be produced.
The volume of carbon dioxide produced is 14L
