Question

Calculate the weight of 100 ppm solution required to create 15 g of each of the following: 1 ppm, 5 ppm, 10 ppm, 20 ppm, 30 ppm and 40 ppm Mg ion

Answer 1

Here concenrtaion is given in ppm

C1V1= C2V2

For 1 ppm

100 ppm * v2 = 1ppm *15 g

V2= 0.15 g

For 5 ppm

100 ppm * v2 = 5 ppm *15 g

V2= 0.75 g

For 10 ppm

100 ppm * v2 = 10 ppm *15 g

V2= 1.50 g

For 20 ppm

100 ppm * v2 = 20 ppm *15 g

V2= 3.00 g

For 30 ppm

100 ppm * v2 = 30 ppm *15 g

V2= 4.50 g

For 60 ppm

100 ppm * v2 = 60 ppm *15 g

V2= 6.00 g
