Question

How many molecules are in 0.0124 mol of CH2O

Answer 1

There are 0.0747×
`10^(23)` molecules in 0.0124 moles of
`C H_(2) O`.

Step-by-step explanation:

We know that 1 mole of any element is equal to Avagadro's number of molecules present in that element. So in this case, it is stated that 0.0124 moles of
`C H_(2) O` is present. Then the number of molecules will be obtained by multiplying the number of moles with Avagadro's number.

No. of molecules = No.of moles × Avagadro's number

No.of molecules = 0.0124×6.022×
`10^(23)` molecules =0.0747×

Thus, 0.0747×
`10^(23)` molecules of
`C H_(2) O` are present in 0.0124 moles of
`C H_(2) O`.
