Hi again,

I'm going through a chemistry textbook that (unfortunately) doesn't have an answer key.

Question: Determine the number of moles of N atoms in 43.5 g of Mg(NO₃)₂.

My answer:

43.5 g Mg(NO₃)₂ x (1 mol Mg(NO₃)₂ / 148.315 g Mg(NO₃)₂) x (2 mol N / 1 mol Mg(NO₃)₂) = 0.587 mol N

Is that correct? And I'm sorry if this type of question is not allowed on the forum, I'm fairly new to this.

Thanks

Edit: I realized the significant digits were off in my original calculation

Your answer looks good.
