3.15 g of an unknown gas at 35 °c and 1.10 atm is stored in a 1.85-l flask. what is the density of the gas? what is the molar mass of the gas?

Explanation:

Hello,

In this case, one uses the ideal gas equation:

By solving for moles in terms of mass and molar mass one obtains:

On the other hand, the density is easily computed as shown below:

Best regards.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
