Question

Find number of gram equivalent present in 3 moles of H2SO4? ​

Answer 1

Answer:

Molar mass of H 2 SO

4 =98 g

As we know, Molecular weight of a substance =1 mole

Weight of a substance = Number of moles×Molecular weight =0.2×98=19.6 g.

Answer 2

Given:

• The number of moles $H_{2} SO_{4}$ is = 3
• The molecular weight of $H_{2} SO_{4}$ = 98u

Formula used:

• Gram equivalents of $H_{2} SO_{4}$ = Molecular weight/n
• Where n = number of replaceable hydrogen atoms.

Explanation:

• Gram equivalents = 98/2 = 49

So the number of gram equivalent present in 3 moles of $H_{2} SO_{4}$ is 49.

Gram equivalents:

• the quantity of an element, group, or compound whose mass, expressed in grams, is equal to its weight, expressed in kilograms.
• The quantity of the chemical is measured in grams equivalents.
• The valency factor, also known as the n-factor, can be computed by multiplying the number of moles of the material present.
• The amount of a chemical that totally interacts with 8 grams of oxygen is its equivalent mass.
