Heres a problem on a take home quiz I am doing, but i can't figure out how to get past the first step?!
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?!
