Answer:

184.3g

Step-by-step 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
(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
