Question

How do I determine the mole fraction of manganese(II) fluoride in a 9.25 M aqueous solution of manganese(II) fluoride. The density of the solution is 1.04 g mL-1.

Answer 1

determine the moles of water and the moles of MgF2, then use the equation

Answer 2

How do I find the moles.

Answer 3

Do I use M=n/V with m=n*Mm

Answer 4

yeah, you might also have to use \(\rho=\dfrac{m}{V}\) since you're given the density

Answer 5

Thank you

Answer 6

you're welcome

Answer 7

Do I assume volume is = to 1L

Answer 8

yeah, it makes things easier. any volume works though

Answer 9
