Question

(C) Number of moles of glucose = $\frac{0.9 \ g}{180 \ g/mol} = 0.005 \ mol$. Number of hydrogen atoms in glucose = $0.005 	imes 12 	imes N_A = 0.06

Vedclass · Accepted Answer

Hydrogen atoms in $0.30 \ g$ ethane $(C_2H_6)$ $(M_w = 30 \ g/mol)$

Vedclass · Answer

(C) Number of moles of glucose = $\frac{0.9 \ g}{180 \ g/mol} = 0.005 \ mol$. Number of hydrogen atoms in glucose = $0.005 	imes 12 	imes N_A = 0.06 \ N_A$. Now,checking option $C$: Number of moles of ethane $(C_2H_6)$ = $\frac{0.3 \ g}{30 \ g/mol} = 0.01 \ mol$. Number of hydrogen atoms in ethane = $0.01 	imes 6 	imes N_A = 0.06 \ N_A$. Since the number of hydrogen atoms is the same,the correct option is $C$.

The number of hydrogen atoms in $0.9 \ g$ glucose $(C_6H_{12}O_6)$ $(M_w = 180 \ g/mol)$ is same as
