when the oxide of arsenic is heated it sublimes and becomes a gas. at 650oc and a pressure of 690mmHg the 0.927g sample of the oxide has a volume of 194cm3.
calculate the volume,in cm3, that the sample would have at the same temperture (650oc) but at a pressure of 760mm Hg
P1V1 = P2V2
Post your work if you want us to chekc it.
