Key Idea: One mole = molecular mass in gram = 22.4 L at STP text= text6 text.0 text.23× 1023 atoms/molecules/ions Molecular mass of CH4=12+1× 4=16 ∴ 16 g of CH4=6.023× 1023 molecules of CH4 ∴ 16 g of CH4 has 4 g atoms of hydrogen

Q. One mole of $C H_{4}$ contains

4 g atoms of hydrogen

3.0 g atoms of carbon

$6.02 \times 10^{23}$ atoms of hydrogen

$1.81 \times 10^{23}$ molecules of $C H_{4}$

Key Idea: One mole = molecular mass in gram = 22.4 L at STP $= 6 .0 .23 \times 10^{23}$ atoms/molecules/ions Molecular mass of $C H_{4} = 12 + 1 \times 4 = 16$ $∴$ $16 g$ of $C H_{4} = 6.023 \times 10^{23}$ molecules of $C H_{4}$ $∴$ 16 g of $C H_{4}$ has 4 g atoms of hydrogen

Q. One mole of CH4​ contains

4 g atoms of hydrogen

3.0 g atoms of carbon

6.02×1023 atoms of hydrogen

1.81×1023 molecules of CH4​

Key Idea: One mole = molecular mass in gram = 22.4 L at STP =6.0.23×1023 atoms/molecules/ions Molecular mass of CH4​=12+1×4=16 ∴ 16g of CH4​=6.023×1023 molecules of CH4​ ∴ 16 g of CH4​ has 4 g atoms of hydrogen

Q. One mole of $C H_{4}$ contains

$6.02 \times 10^{23}$ atoms of hydrogen

$1.81 \times 10^{23}$ molecules of $C H_{4}$

Key Idea: One mole = molecular mass in gram = 22.4 L at STP $= 6 .0 .23 \times 10^{23}$ atoms/molecules/ions Molecular mass of $C H_{4} = 12 + 1 \times 4 = 16$ $∴$ $16 g$ of $C H_{4} = 6.023 \times 10^{23}$ molecules of $C H_{4}$ $∴$ 16 g of $C H_{4}$ has 4 g atoms of hydrogen
