64 grams of oxygen contain how many moles of oxygen?
Three moles
Two moles
One mole
16 moles
The following formula may be used to determine how many real moles of oxygen are contained in 64 grams of oxygen:
Inputting the values provided yields:
2 mol is the number of moles.
Consequently, 64 grams of oxygen contain 2 moles of oxygen.
As is common knowledge, the weight of the material divided by its molecular weight yields the number of moles of a gas. Hence, 64 grams divided by 32 grams equals two moles in the case of oxygen.
