What Is the Molarity of 468 mg MgI2 in a 50 ml Solution?

468 mg MgI2 in 50 ml solution, determine molarity.

.0297
.0337
.0930
.0107
.0651

i did not check my work but i got .337, not .0337.

i asked the professor about it and she assured me the correct answer was there, so i just marked .0337.

Lucky guess. I get 0.0337
0.468 g of Mgl2 is 0.001683 moles and 0.001683 moles / 0.05 L is 0.0337 molarity
