How many moles are there in 2g of oxygen?
We know that 2g of O2 has 0.0625 moles of O2. That means that the number of O2 molecules present in 2g of O2 is equal to 0.0625*NA.
What is the number of atoms in 2g of water?
Answer. O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.
