Frequent question: How many moles are there in 5g of sodium?

How many moles is 5 grams?

How many moles are 5 grams of calcium ? (Atomic mass of calcium =40u). Thus, there are 0.125 mole in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium. In the above case, mass of element is 5 grams and molar mass of element is 40g/mol.

How many moles is 5g of water?

5/18 moles for 5 grams of water.

How many moles are there in 5g of calcium?

Molar mass of Calcium=40.078 g/mol. So numbers of moles =5.00/40.078=0.125 mol.

How many atoms of sodium are there in 0.2 moles sodium atoms?

We know that 1 mole of atoms contains 6.022×1023 atoms. Thus, 0.2 mole of sodium element has 12.044×1022 atoms in it.

How many moles are in sodium chloride?

One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.

How do you find moles of sodium chloride?

One mole of sodium (Na) is 22.99 g, and 1 mole of chlorine is 35.45 g. For sodium chloride (NaCl) they are in a ratio of 1:1 so the molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol.
