What are the concentrations in mass of the following solutions:
a) a 200mL aqueous solution containing 4.26g sodium solfate.
b) a 2.00 L aqueous solution containing 107.0g ammonium chloride NH4Cl.
Plz can give me someone the answers for BOTH and the steps how you did it plzzzzzz :)
Re chemistry -
Don't we need the density? I don't know the mass of 200 mL of solution.
