1. . What mass of magnesium chloride is there in 1dm^3 of a 1mol/dm^3 solution? The formula mass of magnesium chloride is Mgcl2.
2. I'm not sure but the formulas

concentration (mol/dm^3) = number of moles / volume(dm^3)
number of moles x Mr (of MgCl2) = mass

might help?
3. Yeah what the above user said is correct.

Thank you so much I must have been doing it right because that is what I was doing but wanted to make sure if I was right , so the answer would be 95 right but what unit should I give? Thanks a lot

It depends what the questions is asking for either g/dm^3 or mol/dm^3 but for this I think g/dm^3
