Question

equal volume of two substance of density d1 and d2 are mixed together. what is the density of the mixture. ​

Answer 1

Answer:

(d1 + d2)/2

Step-by-step explanation:

d1 = m1/v

d2 = m2/v

after mixing

d3 = m3/v3 = m3/2v = (m1+m2)/2v = 1/2(m1/v + m2/v) = (d1 + d2)/2

Answer 2

$\bold {Density\ of\ mixture = \frac{M_1+M_2}{2V_1}}$

Step-by-step explanation:

Let the volume of A =$V_1$

Mass of A =$M_1$

Density of A = $D_1$

Volume of B =$V_2$

Mass of B = $M_2$

Density of B =$D_2$

Now,According to question,

Volume of A = Volume of B

We know that,

$Volume = \frac{Mass}{Density}$

So,

$\frac{M_1}{D_1} = \frac{M_2}{D_2}$

$\frac{D_1}{D_2} = \frac{M_1}{M_2}$

Now,Density of mixture = $\frac{M_1+M_2}{V_1+V_2}$

                                        = $\frac{M_1+M_2}{2V_1}$

Hence,$\bold {Density\ of\ mixture = \frac{M_1+M_2}{2V_1}}$
