100%

A sample of 8.8 g of methanol, CH₃OH_(l), is added to a 1.00 L flask, whereby the flask is sealed and heated to 75 °C. All the liquid converts to gas after heating for 20 minutes. [melting point of CH₃OH = -98 °C, boiling point of CH₃OH = 64.7 °C, density of CH₃OH_(l) = 0.791 g/mL]

What is the partial pressure of the heated methanol gas in the flask?
What is the density, in g/L, of the gaseous methanol at 75 °C?
What is the density, in g/L, of the gaseous methanol at 68 °C?
What mass of methanol gas is in the flask at 75 °C?
