what mass of solution is contained in 417 mL of a 0.314 M magnesium flouride solution? omg im so stuck!

mass of MgF2 = 24+2*19 =24+38=62
1L of 0.314M of MgF2 = 19.468 g MgF2
and 417mL = 0.417 contains 19.468*0.417=8.12 g MgF2

417ml x 1L x 0.314moles x Atomic mass g
1 1000ml L moles
you have to know the total atomic mass of magnesium flouride.
it's hard to type equations in here. When showing your work just remember to change ml to L. L to moles (molarity) and then moles to grams
