Question

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

Answer 1

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

Step-by-step 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 =
`(1)/(6.023 * 10^(23))`

Number of moles in
`5.22 * 10^(22)` molecules of glucose =
`(5.22* 10^(22))/(6.023 * 10^(23))` =
`0.083` moles

Weight of
`0.083` moles

`= 0.083 * 180\\= 15.08`grams
