nordsb [41]

The mass of is K2CrO7 in the 250 ml of solution is mathematically given as

x=1.25mg of K2CrO7.

Hence, 250 ml of the solution will contain 1.25mg of K2CrO7

<h3>The mass of is K2CrO7</h3>

Question Parameters:

The total of potassium dichromate are there in a 250 mL bottle filled with 5 ppm solution

Generally the mass of k2CrO7  is mathematically given as

x=\frac{5mg of k2CrO7  *250ml of solution}{1000ml of solution}

x=1.25mg of K2CrO7

Therefore,

250 ml of the solution will contain 1.25mg of K2CrO7
