To find the mass of oxygen gas at STP, we can use the ideal gas law and the molar mass of oxygen. The molar volume of a gas at STP is 22.4 L/mol, and the molar mass of oxygen (O2) is 32 g/mol. Using the formula:

mass = molar mass * moles

moles = volume / molar volume

Substitute the values:

moles = 1.25 L / 22.4 L/mol moles ≈ 0.0558 mol

mass = 32 g/mol * 0.0558 mol mass ≈ 1.78 g

So, the mass of 1.25 L of oxygen gas at STP is approximately 1.78 grams.
