Agas occupies a volume of 140 ml at 35.0 c and 97 kpa. what is the volume of the gas at stp

We first need to find the number of moles of gas  at the conditions given. we have to apply ideal gas law equation to find the number of moles
PV = nRT
where 
P - pressure - 97 kPa
V - volume - 0.140 x 10⁻³ m³
n - number of moles 
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 273 + 35 = 308 K
substituting these values in the equation 
97 000 Pa x 0.140 x 10⁻³ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 308 K
n = 5.30 x 10⁻³ mol

at standard pressure and temperature conditions,
1 mol of gas occupies 22.4 L 
therefore 0.00530 mol - 22.4 L/mol x 0.00530 mol 
the volume occupied - 0.1187 L 
volume of gas at STP is  118.7 mL
