Question

In the laboratory, a student adds 47.2 mL of water to 16.5 mL of a 0.605 M hydrobromic acid solution. What is the concentration of the diluted solution

Answer 1

The Concentration of dilute solution is 0.1567M

Step-by-step explanation:

The concentration of the diluted solution is shown below:

Given that

M_1 = 0.605M

V_1 = 16.5 ml

M_2 = ?

V_2= 47.2 + 16.5 = 63.7mL

Now for dilution

As we know that

M_1 × V_1 = M_2 × V_2

0.605 × 16.5 = M_2 × 63.7

So,

M_ 2 = 0.1567M

Hence, the Concentration of dilute solution is 0.1567M
