Can you help me with this please - Temp - 650 Pressure - 690mm Hg mass - 0.927g volume - 194cm3 How do I calculate the volume of the gas at a different temp? & at a different pressure? You can do this two ways. The simplest is P1V2/T1 = P2V2/T2

If the arsenic is 76% and oxygen is 24% how would I calculate the chemical composition of of the oc=xide of arsenic that has been formed? Divide 76 by the atomic weight of As (which is 74.92) and 24 by the atomic weight of O (which is 16.00). The two new numbers that you get w...
