How to convert it to mol?

amount of 2-Bromopropane used is 1.13 mL
which is 1.48 g now how you convert it to mol


same for 4-methoxyacetophenone i need to find mL and mol
only thing i have is 0.753 g

Answer:
Woah, interesting compound names. Okay, in order to convert a weight into moles, you'll need the molecular weight of each of the compounds by summing up the molecular weights of each atom of each element in one molecule of the compound. Elemental molecular weights can be found on most periodic tables. 2-Bromopropane is,basically, C3H7Br. 3C+7H+1Br=123.004
4-methoxyacetophenone is basically C9H10O2. 9C+10H+2O=150.19

Now, you divide the mass of your substance by the compound's molecular weight.
1.48/123.004 = .0120 mol 2-Bromopropane.
.753/150.19=.00501 mol 4-methoxyacetophenone

As for volume, you'll need the density of the methoxyacetophenone (which is 1.094 g/cm^3) and then divide the mass of the sample by the density.

Since 1mL=1cm^3,

.753/1.094=0.688 mL 4-methoxyacetophenone.

Unless there's more to the problem than just this. Then the volume might change.

EDIT: Whoops, sorry. Got the equation wrong. Corrected it. It should be .00501 mol 4-methoxyacetophenone
For 2-bromopropane divide 1.48 g by its molecular weight. This will give you the number of moles. For 4-methoxyacetophenone divide 0.753 g by its density in g/mL (you will have to look this up). This will give you the number of milliliters. To get the number of moles do it just like above. Divide 0.753 g by its molecular weight to get the number of moles. Hope this helps you out.
