Question

How màny hydrogyen àtoms are there in 60 gràms of ethàne .​

Answer 1

GiVEN

• 60 grams of Ethane

TO FiND

• Number of Hydrogen atoms in ethane

SOLUTiON

Molar mass of C2H6

• 2×12+6×1
• 24+6
• 30gm

Mole = molar mass / mass

Mole = 60g / 30g = 2mole

USiNG UNiTARY METHOD

1 mole of ethane (C2H6) = 6 hydrogen atoms = 30 grams of C2H6

★ There are 12 hydrogen atoms in 30 gm of ethane.

Answer 2

Answer:

molar mass of ethane

2×12+6×1

24+6

30gm

Mole = molar mass / mass

Mole = 60g / 30g = 2mole

1 mole of ethane = 6 hydrogen atoms = 30 grams of ethane

so There are 12 hydrogen atoms in 30 gm of ethane.

hope it helps you
