Astudent has a sample of isopropanol (c3h7oh) that has a mass of 78.6 g. the molar mass of isopropanol is 60.1 g/mol. how many moles of isopropanol are contained in this sample?

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
