I'm not so sure if I got the right answer. I got 95.3g. But there are various answer like: 70.0g, 59.8g, 95.2g, 125.9g, and 24.3g. So which one is the correct answer.

Since 95.2 is one of your choices, I'd go with that one. Depending on how and when you round your answers, they'll often be off in the last significant digit by one or two.

First find the number of moles of magnesium: divide 10 by the molar mass of magnesium. Take this value and multiply it by the molar mass of magnesium chloride, and by the molar mass of hydrogen (which is 2) and you're done.

The mass of one mole of magnesium chloride MgCl2 :
= 24 + (2× 35.5) = 95 g.

you need the atomic mass of the elements involved so here they are:
Magnesium: 24
Chlorine: 35
Now you have one atom of Mg and 2 Cl so take 24+35*2 and thats yer answer/ 94 is what I get, but my amu measurements were slightly off so you're closer than me
