The density of helium gas at 0°C is 0.179 kg/m^3. The temperature is then raised to 100°C, but the pressure is kept constant. Assuming that Helium is an ideal gas, calculate the new density of the gas.

Heres the equations i have:

P1V1 / T1 = P2V2 / T2

In order to work this equation i need volume, but i have a density, here's the equation i think i need:

roe = m / V

(density = mass / volume)

How do i work this if i don't have mass or volume?!
