Question

Calculate the number of molecules in 16g of H2CO3

Answer 1

Answer:

1 mole =6.023×10 root 23.

16 x 10root 23=160root 23 mole.

Explanation:

1 mole have a digit and it's multiply by 10 root 23.

so, the answer is in root

Answer 2

Given:

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

The number of molecules in 16g of H2CO3 is 0.258moles
