Question

Equal masses of two substances who density are
are 0.3 g/cc and 0.9g/cc are mixed homogeneous find the density of the mixture
​

Answer 1

let the mass of both the substance be m

then

we know d=m/v

d=2m/(m/.3 +m/.9)

d=2m/(10m/3 +10m/9)

d=2m/{(30+10)m/9}

d=2m/40m/9

d=2×9/40

d=9/20

d=.45

hope it helps

Answer 2

Answer:

Explanation:

Hi answer is 0.9,

Equal masses the formula is

2d1d2/d1+d2

Now let's do 2*0.3*0.9/0.3+0.9

0.54/1.2

So the answer is 0.45
