Question

How many molecules are in there in 2.5 moles of glucose C6H12O6?

Answer 1

Answer

$1.5055\times10^{24}\text{ molecules}$

Explanation

We need a conversion factor that will converts from moles of glucose, C6H12O6 to molecules of glucose.

That is, one mole of any substance contains 6.022 x 10²³ molecule of that substance.

$\begin{gathered} 1\text{ mole = 6.022}\times10^{23} \\ 2.5\text{ moles }=\frac{6.022\times10^{23}\times2.5}{1}=1.5055\times10^{24}\text{ molecules} \end{gathered}$

1.5055 x 10^24 molecules of glucose are in 2.5 moles of glucose C6H12O6
