A liquid of volume 2.00 m3 and density 1.00 x 103 is mixed with 3.00 m3 of another liquid of density 8.00 x 103kg m-3. Calculate the density of the mixture [Assuming there is no chemical reaction]

A.

5.20 x 102 kg m-3

B.

1.13 x 103 kg m-3

C.

8.80 x 102 kg m-3

D.

5.20 x 102 kg m-3

Correct answer is D

\(V_T = 5m^3, m_1 = 2 \times 1 \times 10^3 = 2 \times 10^3\)

\(M_2 = 3 \times 8 \times 10^3 = 24 \times 10^3\)

MT = 26 x 103

D = \(\frac{m}{v} = \frac{26 \times 10^3}{5} = 5.2 \times 10^3\)
