Question

How many moles are present in $540g$ of glucose $\left(C_6{H}_{12}{O}_6\right)$?

• A. $2$ moles
• B. $3$ moles
• C. $4$ moles
• D. $1$ mole

Answer 1

Answer: (B)

$3$ moles

Glucose $\left(C_6{H}_{12}{O}_6\right)$

Given mass of glucose = 540g

molar mass of glucose = 180g/mol

so, number of moles = $\frac{givenmass}{molarmass}=\frac{540}{180}=3$

so, number of moles present in 540g of glucose will be 3 moles.
