Question

The number of moles of atoms of carbon and hydrogen present in 4g of methane are ?

I'll mark brainlist if good explanation​

Answer 1

Answer:

Molar Mass of 1 molecule of methane(CH4) = 12 + 4 = 16g/mol

That is, 16g if CH4 contain 1 mole molecule of it

= 6.022×10²³ molecules of CH4 which consists of 1 mole of C atoms and 4 moles of H atoms.

=> 4 g of CH4 contains 1/4 × 6.022×10²³ molecules

= 1.5055×10²³ molecules of CH4

= 1.5055×10²³ C atoms and 6.022×10²³ H atoms
