Question

What is the mass in grams of KBr in 0.400 L if a 0.350 M solution?

Answer 1

16.464 g

Step-by-step explanation:

Given,

Volume of KBr solution, v = 4L

concentration, s = 0.35 M

Molecular mass of KBr, M = 79.9 + 39 = 118.9 g

Now we know,

`w = svm` when volume in litre

⇒
`w = 0.35 X 0.4X118.9` = 16.646g
