Expert Solution

Step 1

Hello. Since the question contains multiple parts, the first part is solved. In case the solution for other parts is required, then repost the entire question and specify the part that has to be solved.

Step 2

1)Computing Volume at NTP,

$\begin{array}{rcl} \frac{P_{1} V_{1}}{T_{1}} & = & \frac{P_{2} V_{2}}{T_{2}} \\ \frac{752 \times 571}{298} & = & \frac{760 \times V_{2}}{273} \\ V_{2} & = & 517.59 mL . \end{array}$
