Answer:
The mass of 3, 10 moles of MgCl2 is 295, 43 grams.
Explanation:
We calculate the weight of 1 mol of MgCl2:
Weight 1mol of MgCl2= weight Mg + (weight Cl)x 2=
24, 3 grams + 2 x 35, 5 grams = 95, 3 grams/mol MgCl2
1 mol MgCl2 ---------------95, 3 grams
3,1 mol MgCl2---------------x=(3,1 mol MgCl2x95,3 grams)/1 mol MgCl2
x=295, 43 grams
