Question

Calculate the number of molecules of H2SO4 in 1mL if its specific gravity is 1.84?

Answer 1

Answer:

1.13 X 10²²

Explanation: Density=1.84=mass/1ml

mass of H₂SO₄ is 1.84 gm

mole= 1.84/98 = no. of molecules / 6.02 X 10²³

= 1.13 X 10 ²²

Answer 2

Answer:

sulphuric acid has gravity is 1.84 ml

so the mass of acid 1.84 grams

molar mass of H2SO4 = 98 u

number of moles = given mass / molecular mass

= 1.84 / 98

= 0.01878 mole

number of molecules = mole × NA

= 0.01878 × 6.023 × 10^23

= 1.1306 × 10^22

This is your answer..
