Question

calculate molecular mass of perchloric acid​

Answer 1

Answer:

Mass of perchloric acid = 100.5g

Explanation:

$\diamond$ Perchloric acid is a mineral acid

$\diamond$ This is a strong acid which is much stronger than HNO₃ or H₂SO₄

$\diamond$ The chemical formula of perchloric acid is HClO₄

$\diamond$ The structure of perchloric acid is given below

$\diamond$ We know that,

Mass of 1 hydrogen atom= 1g

Mass of 1 chlorine atom= 35.5g

Mass of 1 oxygen atom = 16g

$\diamond$ Hence,

Mass of perchloric acid

= Mass of 1 hydrogen atom+Mass of 1 chlorine atom+Mass of 4 oxygen atom

= 1 + 35.5 + 4*16

= 1 + 35.5 + 64

= 100.5g
