Physics Help

Hi can someone help with these questions please.

The oven of a dometic cooker has a volume of 0.10m^3. The pressure in the oven is 1.0 x 10^5 Pa (1 Atmosphere).

i) Calculate the mass of air in the oven at 27 degrees celsius.

Molar mass of air = 0.030 kg mol^-1

ii) At constant atmospheric pressure, the density of the air at 227 degrees celsius is x times the density of air at 27 degrees celsius. Calculate the value at x.

I can't remeber the moles equation so can't do it. I'd be greateul for help.
