Question

One liter of 750ppm solution of KClO3 contains how many grams of K+​

Answer 1

Answer:

7AM the name gopi says I am

Answer 2

Explanation:

g/m3 = 1 mg/L =1 ppm

1 g/cm3 = 1,000,000 g/m3

0.77g/cm3 = 770,000 g/m3

770,000 g/m3 = 770,000 ppm

To prepare 1ppm of hexadecane in 1000 ml of water,

M1V1 = M2V2

(770000 ppm)V1 = (1ppm) 1000ml

V1 = 0.0013ml or 1.3 µl

If u don’t have the micro-pipette, u can prepare 1000ppm of hexadecane first then can dilute to 100, 10 and finally 1 ppm.
