Alab technician needs to create 570.0 milliliters of a 2.00 m solution of magnesium chloride (mgcl2). to make this solution, how many grams of magnesium chloride does the technician need?

Hey there!:

Molar mass MgCl2 = 95.211 g/mol

Volume of solution in liters:

570.0 mL / 1000 => 0.57 L

Number of moles:

n = M * V

n = 2.00 * 0.57 => 1.14 moles of MgCl2

Therefore:

1 mol MgCl2 95.211 g

1.14 moles MgCl2 ??

mass of MgCl2 = 1.14 * 95.211

mass of MgCl2 = 108.54 g

Hope that helps!
