= 86.5 g

Explanation:

Using the equation;

PV = n RT

where P is the pressure, 464 kpa or 4.58 atm

V is the volume, 13.0 l

n is the number of moles

R is the ideal gas constant, 0.0821 atm L/mol/K

T is the temperature, 112 + 273.15 = 385.15 K

Therefore;

n = PV/RT

n = (4.58 * 13) / (0.0821*385.15)

= 1.883 moles

The mass will be;

= 1.883 moles * 46.0 g/mol

= 86.57 g

= 86.5 g
