Answer to Question #70614 in Chemistry for sentrina

Question

a solution consisting of 290g of NaCl , was made up to a volume of 2500 cm3 with water. what is the normality of the solution? (use 58.4428 g as the molecular mass of NaCl)

a)0.504N
b)1.160N
c)1.985N
d)2.338N

Answer 1

C n = n/V
n = m/e
e = M/w
e (NaCl) = 58.4428 / 1 = 58.4428
n (NaCl) = 290 / 58.4428 = 5 g-ekv
C n = 5 / 2500 = 2 n
