A balloon is at 15oC,
150 kPa, and is 520
mL in volume.
Calculate how
many grams of CO2
gas are in the balloon

Approximately , assuming that acts like an ideal gas.

Explanation:

Look up the ideal gas constant:

.

Convert the unit of temperature, pressure, and volume to standard units:

Assume that the here acts like an ideal gas. Apply the ideal gas law to find the number of moles of

.

Look up the following relative atomic mass data on a modern periodic table:

Calculate the molar mass of :

.

The mass of that of in this balloon would be:

.
