Answer:

318.749g

Explanation:

The find the mass,

We use this formula

Number of mole = mass/ molar mass

Since number of mole = 3.25mol

Let the number of mass be x

The molar mass of H2SO4

H - 1.00784 * 2= 2.01568

S - 32.065

O - 15.999 * 4 = 63.996

Note there are 2 moles of H and 4 moles of O and 1 mole of S

Molar mass of H2SO4 = 2.01568 + 32.065 + 63.996

= 98.07668g/mol

Number of mole= 3.25mol

3.25 = x / 98.07668

x = 3.25 * 98.07668

x= 318.749g

Hence, the number of mass is 318.749g

Hope it will help you.

The chemical formula for sulphuric acid is H2SO4

The molar mass of H2SO4 is calculated as;
2(1)+32+4(16)
98g/mol

Amount of substance =mass/molar mass

Mass=Molar mass*Amount if substance
Mass=98*3.25
Mass=318.5g

I hope this helps
