What is the mass of 3.10 moles of magnesium chloride, MgCL2?

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 MgCl2x=(3,1 mol MgCl2x95,3 grams)/1 mol MgCl2

x=295, 43 grams

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

the answer would be a
