Question

The number of moles of hydrogen in $1.8$ g $C_{6} H_{12} O_{6}$ is $x \times 10^{- 2}$ . Then, the value of $x$ is _______.

Open in App

Solution

Molar mass of $C_{6} H_{12} O_{6} = 180 g$

Therefore, moles of hydrogen in 1 mole (180 gm) of $C_{6} H_{12} O_{6} = 12,$

Moles of hydrogen in 1.8 g of $C_{6} H_{12} O_{6}$ = $\frac{12}{180} \times 1.8$

Moles of hydrogen $= 0.12$ moles or $12 \times 10^{- 2}$

Thus the value of $x = 12$

The number of moles of hydrogen in 1.8 g C6H12O6 is x×10−2. Then, the value of x is _______.

Molar mass of C6H12O6=180 gTherefore, moles of hydrogen in 1 mole (180 gm) of C6H12O6=12,Moles of hydrogen in 1.8 g of C6H12O6 = 12180×1.8Moles of hydrogen =0.12 moles or 12×10−2Thus the value of x=12

The number of moles of hydrogen in $1.8$ g $C_{6} H_{12} O_{6}$ is $x \times 10^{- 2}$ . Then, the value of $x$ is _______.

Molar mass of $C_{6} H_{12} O_{6} = 180 g$

Therefore, moles of hydrogen in 1 mole (180 gm) of $C_{6} H_{12} O_{6} = 12,$

Moles of hydrogen in 1.8 g of $C_{6} H_{12} O_{6}$ = $\frac{12}{180} \times 1.8$

Moles of hydrogen $= 0.12$ moles or $12 \times 10^{- 2}$

Thus the value of $x = 12$
