Question

State Boyle's Law and Charle's Law.
Derive the relation PV = nRT. An evacuated glass vessel
weighs 50 g when empty, 148 g when filled with a liquid of
density 0.98 g/mL and 50.5 g, when filled with an ideal gas at
760 mm Hg at 27°C. Determine the molecular mass of the
gas. How many numbers of molecules are present in 12.3 g
show with solution​

Answer 1

Answer:

Mass of ideal gas =50.5−50=0.5 g

Mass of liquid =148−50=98 g

Volume=

=

0.98

98

=100 mL or 0.1 L

For the gas,

PV=

0.5

×0.0821×300

or M=123.15≈123
