please answer parts A,B, and C with as much work shown as possible!

Oxygen is a product of the decomposition of mercury(II) oxide as shown below. 2HgO(s)2Hg()+O2(g) Assume that 4.20 grams of HgO was used in this reaction. To determine the number of moles of oxygen gas formed, you need to know the number of moles of HgO reactant was used. What quantity in moles of HgO were used? What quantity in moles of O. gas will be formed in this reaction? What volume (in L ) of O2 will be produced from the decomposition of 4.20g of HgO assuming a pressure of 1.50atm and a temperature of 122.0C ? Remember the gas constant, R, is 0.08206Latm/molK
