Take 1 kg dry ice. Heated to a temperature of 100 C. How much carbon dioxide will you get?

Given:
m (dry ice) = 1 kg = 1000 g

To find:
V (CO2) -?

Decision:
1) It should be noted that dry ice is solid CO2;
2) Calculate the molar mass of CO2, which will be numerically equal to the molecular mass:
M (CO2) = Mr (CO2) = Ar (C) + Ar (O) * 2 = 12 + 16 * 2 = 44 g / mol;
3) Calculate the amount of substance CO2:
n (CO2) = m (CO2) / M (CO2) = 1000/44 = 22.72 mol;
4) Calculate the volume of CO2 (under normal conditions):
V (CO2) = n (CO2) * Vm = 22.72 * 22.4 = 508.9 liters.

Answer: The CO2 volume is 508.9 liters.
