Help i have a chemistry assignment due tom. and i cant solve any of these probelms that i ihave left.
Can you please help with these four?
My base is Al(ClO3)3 aluminum chlorate
How many grams of the compound would need to be dissolved in 750ml of the solvent to make a 2.5M solution?
What is the molarity of a solution containing 355 grams of solute in 1550ml of solution
What is the molality of a solution containing 15.0 grams of solute mixed with 55.0 grams of solvent.
How many grams of the compound would need to be dissolved in 5500grams of solvent to make a 17.5m solution.

I'm not doing it all
Remember that
1M = 1mol per decimetre/litre cubed
1 mol = mass/molecular mass
molecular masses are the sum of the atoms in the molecule, obtained from the periodic table.
Now you can do it yourself
