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

Sagot :

Answer: There are [tex]6.926\times 10^{23}[/tex] 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 [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the molecules, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadro's number}}[/tex]

[tex]1.15=\frac{x}{6.023\times 10^{23}}[/tex]

[tex]x=1.15\times 6.023\times 10^{23}=6.926\times 10^{23}[/tex]

Thus there are [tex]6.926\times 10^{23}[/tex] molecules of glucose.
