40m³ of liquid is mixed with 60m³ of another liquid Q. If the density of P and Q are 1.00kgm^-3 and 1.6kgm^-3 respectively, what is the density of the mixture?

0.05kgm^-3

1.25kgm^-3

1.30kgm^-3

1.36kgm^-3

Correct answer is D

M_p = 1 x 40 = 40kg ; mQ = 1.6 x 60 = 96kg

volume of mixture = 40 + 60 = 100m³

mass of mixture = 40 + 96 = 136kg

density of mixture = \(\frac{136}{100}\)

= 1.36kgm³
