Question: 1. C3H8(g) + 5 O2(g) > 3 CO2(g) + 4H2O(g) A. how many 1. C3H8(g) +5 O2(g) > 3 CO2(g) + 4H2O(g)
E. How many moles of oxygen gas are required to form 5.25 x 10^24 molecules of CO2?

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
