Question

Acetylene gas is used in industrial works such as welding metals. The

temperature needed to weld is approximately 2200°C at 1500 psia. Calculate its

density at this given temperature and pressure in kgm per cubic meter

Answer 1

$pV=\frac mMRT,$

$\rho=\frac{pM}{RT},$

$\rho=13~\frac{kg}{m^3}.$
