Pentaerythritol tetranitrate aka petn is one of the most

Question

Pentaerythritol tetranitrate, a.k.a., PETN, is one of the most powerful explosives known. It has a density of 1.77 g/cm³. Find (1) the volume of a 227 g (about 1/2 pound) quantity of the explosive before the explosion and (2) the volume of total gas produced after the explosion. Assume STP conditions:

C(CH₂ONO₂)_{4 (s)} → 2CO_(g) + 4H₂O_(g) + 3CO_2(g) + 2N_2(g)

All numbers immediately following elemental symbols are subscripts. You must show all work to receive credit. (HINT: You can use density to find the initial condition for volume of the solid. You can then use the mol of gaseous products to determine volume of final condition since you know molar volume at STP
