Answer:

The volume of first and second compound are 9.15 ml and 10.85 ml.

Explanation:

Given that,

Density of graphite = 2.25 g/cm³

Volume of mixture = 20.0 mL

Density of first compound = 1.492 g/ml

Density of second compound = 2.890 g/ml

Let the volume of first mixture = x

The volume of second mixture = (20-x)....(I)

We need to calculate the volume of first compound

Using formula of density of mixture

$\rho=\dfrac{V_{1}\rho_{1}+V_{2}\rho_{2}}{V_{1}+V_{2}}$

Where, $V_{1}$ = volume of first compound

$V_{2}$ = volume of second compound

$\rho_{1}$ =density of first compound

$\rho_{1}$ = density of first compound

Put the volume into the formula

$2.25=\dfrac{x\times1.492+(20-x)\times2.890}{x+20-x}$

$45=1.492x+57.8-2.890x$

$45-57.8=1.492x-2.890x$

$12.8=1.398x$

$x=\dfrac{12.8}{1.398}$

$x=9.15\ ml$

We need to calculate the volume of second compound

Using equation (I)

$V_{2}=20-x$

Put the value of x

$V_{2}=20-9.15$

$V_{2}=10.85\ ml$

Hence, The volume of first and second compound are 9.15 ml and 10.85 ml.

Crazy boy [7]

Explanation:

Apply Boyle's Law :-

P1V1 = P2V2

Where P1 is 25 atm
V1 is 3L
P2 is 75 atm
V2 is what we need to find out.

25 × 3 = 75 × V2

$\tt{V_2 = \dfrac{ 25 \times 3}{75}}$

$\tt{V_2 = \dfrac{75}{75}}$

<u>So, the answer is d) Part, 1L .</u>

Hope it helps :)
