Answers

Current values for STP are 0?C or 273.15 K for temperature, and pressure of 10^5 Pa, which is usually written as 100 kPa, or 1 bar.

At these current values, the molar volume of a gas is 22.710 L/mol( earlier 22.4 L/mol)

Number of moles of argon = 97/22.4 = 4.33 Since argon has molar mass of 39.94 g/mol

Mass m = 39.94 x 4.33 = 172.94 g

For oxygen molar mass 32 g/ mol

So mass = 4.33 x 32 = 138.56 g
