Question

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

Answer 1

Mass of H₂SO₄ : 69,972 g

Further explanation

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 :

`\tt mol=(N)/(No)\\\\mol=(4.3* 10^(26))/(6.02* 10^(23))\\\\mol=7.14* 10^2`

mass H₂SO₄ (MW=98 g/mol) :

`\tt mass=mol* MW\\\\mass=7.14.10^2* 98\\\\mass=69,972~g`
