To find the volume of 84.7 g of O2 at 1.07 atm and 37.4 °C, we can use the Ideal Gas Law:

PV = nRT

First, we need to convert the mass of O2 into moles. The molar mass of O2 is 32 g/mol.

84.7 g / 32 g/mol = 2.646875 mol

Next, we can plug in the values into the Ideal Gas Law formula:

V = (nRT) / P
V = (2.646875 mol * 0.0821 L atm/mol K * 310.4 K) / 1.07 atm
V = 68.244 L

Therefore, the volume of 84.7 g of O2 at 1.07 atm and 37.4 °C is 68.244 liters. In scientific notation, this is expressed as 6.8244 x 10^1 L.
