How many moles are in 25 grams of hydrogen?

1 Expert Answer

Hydrogen has an atomic weight of 1; and oxygen has an atomic weight of 16 (check the periodic table for the atomic weights). So, one mole of water has a mass of 16 +1+1 = 18 grams. So, if one mole has a mass of 18 grams, 25 grams would have a mass of 25 grams/ 18 grams per mole or 1.39 moles.

How many moles are in 28g of co2?

Complete answer:

The molecular weight of a material is required to tell an individual how many grams there are in one mole of that chemical substance i.e. molecular weight of any substance contains 1 mole of that substance. Then 28 g of $C{{O}_{2}}$ contains = 0.636 moles of $C{{O}_{2}}$.
