6. a sample of a gas has a mass of 0.527 g. its volume is 0.35 l at a temperature of 88 degree celsius and a pressure of 945 mm hg. find it's molar mass (show your work)

The molar mass of the gas is 35.87 g/mol.

Explanation:

To calculate the mass of gas, we use the equation given by ideal gas:

PV = nRT

or,

where,

P = Pressure of gas = 945 mmHg

V = Volume of the gas = 0.35 L

m = Mass of gas = 0.527 g

M = Molar mass of gas = ? g/mo

R = Gas constant =

T = Temperature of gas =  

Putting values in above equation, we get:

Hence, the molar mass of the gas is 35.87 g/mol.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
