How many grams are there in 4.30 x 10²⁶ molecules of H₂SO₄?

Mass of H₂SO₄ : 69,972 g

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

moles of H₂SO₄ :

mass H₂SO₄ (MW=98 g/mol) :
