How many molecules are in 10.0 g of #O_2# gas at STP?
How many molecules at STP? The same number of molecules in 10.0 g of LIQUID OXYGEN at LOW TEMPERATURES.
You specified a mass of 10.0 g. Clearly, this is a finite number of dioxygen molecules. This same finite number (which is
Of course, at STP, dioxygen is a gas, but 10.0 g is still 10.0 g. We could calculate its volume at STP, which is
STP is irrelevant - it's a detractor. Mass is not dependent on temperature or pressure. The number of molecules of
Determine the molar mass of
You will make the following conversions:
