Answer:

a) 0.15 mol.

b) 8.95 g.

Explanation:

Hello there!

In this case, according to the given information, it is possible for us to infer this problem is solved by using the ideal gas equation:

$PV=nRT$

And proceed as follows:

a) Here, we solve for the moles, n, as follows:

$n=\frac{PV}{RT} \\\\n=\frac{0.50atm*4.5L}{0.08206\frac{atm*L}{mol*K}*178K} \\\\n=0.15mol$

b) for the calculation of the mass, we recall the molar mass of butane, 58.12 g/mol, to obtain:

$0.15mol*\frac{58.12g}{1mol} =8.95g$
