Which of the following molecules has highest number of particles?

Options

A. 8g of `CH_4`
B. 4.4 g of `CO_2`
C. 34.2 g of `C_(12) H_(22)O_(11)`
D. 2g of `H_2`

Answer

D

Explanation

Number of particles in 8g of `CH_4=(6.023 xx 10^(23))/(16) xx 8 = 3.0115 xx 10^(23)`
No. of particles in 4.4 g of `CO_2 = (6.023 xx 10^(23))/(44) xx 4.4 = 6.023 xx 10^(22)`
No. of particles in 34.2 g of `C_(12) H_(22)O_(11)=(6.023 xx 10^(23))/(342) xx 34.2 = 6.023 xx 10^(22)`
No. of particle in 2g of `H_2 = (6.023 xx 10^(23))/(2) xx 2 = 6.023 xx 10^(23)`
