Question

The united stated chemical industry produces more sulfuric acid, in terms of mass, than any other chemical. What is the mass of 3.25 moles of sulfuric acid. Please show work!!!

Answer 1

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

Answer 2

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.
