If you were provided with the density of a gas and asked to find the molecular weight using the ideal gas law, what would the formula be?

A.MW = dT/RP
B.MW = P/dRT
C.MW = RT/dP
D.MW = dRT/P
can someone please help i have like four more questions which i also need help with.

the other four are 	1.What is the molecular weight (molar mass) of a gas with a density of 4.72 g/L at 124°C and 426 torr?
 	
	a316 g/mol
	b274 g/mol
	c282 g/mol
	d85.7 g/mol

	2.What volume is occupied by 45.0 g of CH4 at 345 mm Hg and 35 °C?
 	
	a322 L
	b17.8 L
	c2.51 x 103 L
	d156 L
