What quantity of sodium chloride is contained in a molar solution (1m) of sodium chlo

If the atomic mass of sodium is 23 and the atomic mass chorine is 35.5?? Can anyone explain how this is worked out?

1M solution NaCl will have (23+35.5) 58.5g per litre.

First off, and this might sounds pedantic but it is 1 M - big M for Molar which is moles per liter of mol/l

So, if you are told it is 1 M or 1m/l then you need to work out what the weight of 1 mole is and that is how much will be in one liter!

Also, you could probably just type it into wolfram alpha, but I suspect that is not why you asked...
