5. Calculate the weight of (NHa) P04 needed to prepare 2000 ml of a 1.50 M solution: 6- Two sucrose solutions are mixed. One has a volume of 480 ml and a concentra- tion of 1.50 M C12H22011: the other, 620 ml and a concentration of 1.20 M C122201 What is the concentration of the final solution? 7- Calculate the equivalent weights of the following acids or bases given the following information or equations. a) H2S diprotic c) HgAs04 2H+1 + HAs04-2 b) HNO3 d) CSOHExplanation / Answer
5)
volume , V = 2000 mL
= 2 L
number of mol,
n = Molarity * Volume
= 1.5*2
= 3 mol
Molar mass of (NH4)3PO4,
MM = 3*MM(N) + 12*MM(H) + 1*MM(P) + 4*MM(O)
= 3*14.01 + 12*1.008 + 1*30.97 + 4*16.0
= 149.096 g/mol
mass of (NH4)3PO4,
m = number of mol * molar mass
= 3 mol * 149.096 g/mol
= 447 g
Answer: 447 g
