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: Option D
Explanation
(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)
