How many molecules are there in 10 moles of oxygen?

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 22.4 L × its molar quantity, approx. 8⋅L . There are 1.51×1023molecules O2 in 10.0 g O2 .

How many grams is 10 moles of oxygen atoms?

The molar mass is used to convert grams of a substance to moles and is used often in chemistry. The molar mass of an element is found on the periodic table, and it is the element’s atomic weight in grams/mole (g/mol). If the mass of a substance is known, the number of moles in the substance can be calculated.
