A student wants to make 5.00% solution of rubidium chloride using 0.37 g of the substance. what mass of water will be needed to
chubhunter [2.5K]

Answer:-

7.03 g

Explanation:-

Let the mass of water needed be M.

So total mass = M + 0.37

Now 5% of this solution has 0.37g of rubidium chlorude.

∴ (M +0.37) x (5/100) = 0.37

M +0.37 = 0.37 x 100/5

M + 0.37 = 7.4

M = 7.4-0.37

=7.03

Thus water to be added is 7.03 gram
