Recycle Bin Posted November 26, 2016 Report Share Posted November 26, 2016 I don't understand how to do this question. Would anyone help? Reply Link to post Share on other sites More sharing options...
Msj Chem Posted November 26, 2016 Report Share Posted November 26, 2016 (edited) Convert each mass to amount in mol using the equation n=m/M. Then multiply each of the values by the Avogadro constant 6.02 x 10^23. This will give you the number of molecules of each. You'll find that the compound with the highest molar mass has the lowest number of molecules for the same mass (1g) and vice versa. The answer is A as it has the lowest molar mass and therefore the greatest number of molecules. Edited November 26, 2016 by Msj Chem 2 Reply Link to post Share on other sites More sharing options...
