#### How many grams of solute are in each of the following

Oct 25, 2009 · Since 1 atomic mass unit = 1g/mol, so 1 mol of Al(NO3)3 has 213g. A 3.0M solution has 3mols/L so 3*213g/L or 639g/L. and you have 3.3L of the solution so 3.3*639=2108.7g. Try this for the other question. I got 11.3 (roughly, I rounded in some places). If your teacher is really picky about significant digits, remember to only use 2.
