Question

How many molecules of glucose are in 1.15 mol of glucose, C6H1206?

Answer 1

Answer: There are $6.926\times 10^{23}$ molecules of glucose.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the molecules, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadro's number}}$

$1.15=\frac{x}{6.023\times 10^{23}}$

$x=1.15\times 6.023\times 10^{23}=6.926\times 10^{23}$

Thus there are $6.926\times 10^{23}$ molecules of glucose.
