A) If we have a 4.5 L container of CH 10 gas at a temperature of 178 K and a pressure of 0.50 atm, then how many moles of CaHio do we have?
b) How many grams of C4H1o do we have?

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:

And proceed as follows:

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

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

Regards!

the answer is na (sodium)
