Question

calculate number of mole (a) 16 g of H.CO​

Answer 1

Answer:

the formula of Carbonic Acid is H2CO3.

Molecular Mass (M) of H2CO3 = 62 gram / mole (approx)

Given Mass (m) of H2CO3 = 16 gram

Moles (n) = ?

As formula :

Moles = given mass / molar mass

n = m/M

n = 16 gram / 62 gram per mole

n = 0.258 moles (approx)

Moles (n) = 0.258 moles Answer

Answer 2
