Question

How many grams are in 42.5L of H2SO4

Answer 1

Answer:

184.3g

Explanation:

Given parameters:

Volume of acid  = 42.5L

Unknown:

Mass of acid  = ?

Solution:

We have to assume that this measurement was taken at rtp;

  At rtp;

       1 mole of a substance occupies a volume of 22.4L

 

Therefore,

       42.5L of H₂SO₄ will have $\frac{42.5}{22.4}$  moles  = 1.9moles

To find the mass;

  Mass  = number of moles x molar mass

     Molar mass of H₂SO₄   = 2(1) + 32 + 4(16)  = 97g/mol

 Mass  = 1.9 x 97  = 184.3g
