Question

An evaculated glass vessel weighs 50 g when empty 148 g when filled with a liquid of density 0.98 g/cc and 50.5g when filled with an ideal gas at 760mmHg and 300K CALCULATE the volume of ideal gas at NTP

Answer 1

Answer:

Hope this helps!!

Explanation:

Mass of ideal gas =50.5−50=0.5 g

Mass of liquid =148−50=98 g

Volume=

Density

Mass

=

0.98

98

=100 mL or 0.1 L

For the gas,

PV=

M

w

RT

or

760

760

×0.1=

M

0.5

×0.0821×300

or M=123.15≈123 g
