Question

p^3xq^2=200
what are p and q

Answer 1

Answer:

Suppose atomic masses of P and Q are X and Y respectively.

Molar mass of P

2

Q

3

=2X+3Y

and Molar mass of PQ

2

=X+2Y

∴2X+3Y=

0.15

15.9

....(i) and X+2Y=

0.15

9.3

....(ii) (Moles = Weight/Molecular weight)

Solving these equations, X=26gmol

−1

,Y=18gmol

−1

So, the atomic mass of 6Q is 18.

Hence, Q=3.

Answer 2

Step-by-step explanation:

$p {}^{3} \times q {}^{2} = 200$

$= 2 {}^{3} \times {5}^{2}$

$p = 2 \: \: \: and \: q = 5$
