Question

#1 pls help me complete

Answer 1

Answer:

n = 0.045 mol.

Explanation:

Hello there!

In this case, according to the given problem, we can firstly set up the ideal gas equation as shown below:

$PV=nRT$

Thus, as we are asked to calculate the moles, we proceed as follows:

$n=\frac{PV}{RT}$

Therefore, we plug in the given data to obtain:

$n=\frac{760mmHg*\frac{1atm}{760mmHg}*1.0L}{0.08206\frac{atm*L}{mol*K}*273K} \\\\n=0.045mol$

Best regards!
