Question

If you have 5.22*1022 molecules of glucose (C6H12O6) how many grams is this?

Answer 1

Answer:

5.22*1022 molecules of glucose (C6H12O6)  is equal to 15.08 grams

Explanation:

Number of molecule of glucose in one mole $= 6.023 * 10^{23}$

Now mass of one mole of glucose $= 180$ grams

Number of moles in $6.023 * 10^{23}$ molecules of glucose $= 1$

Number of moles in $1$ molecules of glucose =  $\frac{1}{6.023 * 10^{23}}$

Number of moles in $5.22 * 10^{22}$ molecules of glucose =  $\frac{5.22* 10^{22}}{6.023 * 10^{23}}$  = $0.083$ moles

Weight of $0.083$ moles

$= 0.083 * 180\\= 15.08$grams
