Answer:
17.2 meters
Explanation:
Carbon dioxide (CO2) molecular mass is 44g/mol, then the number of moles of 10000kg carbon dioxide will be:
10,000kg * (1000g/kg)/ (44g/mol) = 227,272moles
The volume of gas in STP is 22.4 L/mol, then the volume of the carbon dioxide will be:
227,272 moles* 22.4L/mol= 5,090,909 L
One liter equal to 0.001 meter cubic. The formula for cube volume is , if the volume is 5090909L then the side of the cube will be:
volume=
5090909L * (0.001 /L)=
side=
side= 17.2m
