A popular brand of cola contains 7.80 g of carbon dioxide dissolved in 1.00 L of soft drink. If the evaporating carbon dioxide is trapped in a cylinder at 1.00 atm and 18.0°C, what volume does the gas occupy?
Hello and thank you for your question.
Let's assume the carbon dioxide an ideal gas, and that the whole 7.80 g have evaporated into the cylinder.
Let's recall the ideal gas formula:
We clear volume:
n is the number of mol of the substance we have.
We can determine it as:
We can find the molar mass of the carbon dioxide on charts.
Now for the constant R is already given as:
We just have to make one small change to apply the formula, convert Celsius into Kelvin:
We proceed to apply the formula:
Good luck!

A cylinder contains 0.250 mol of carbon dioxide (CO2) gas at a temperature of 27.0∘C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The gas is heated until its temperature increases to 127.0∘C. Assume that the CO2 may be treated as an ideal gas. How much work W is done by the gas in this process? What is the change in internal energy ΔU of the gas? How much...
