Answer:
1.1 g Na2SO4
Explanation:
First convert mL to L. Then multiply by the Molarity to get moles, then multiply by the molar mass to get grams.
15 mL x 1 L x 0.50 mol Na2SO4 x 142 g = 1.1 g
10^3 mL 1 L mol Na2SO4
The total pressure is given by
![P_{T} = P_A + P_B + P_C](https://tex.z-dn.net/?f=P_%7BT%7D%20%3D%20P_A%20%2B%20P_B%20%2B%20P_C)
A system a STP will have a total pressure of 101.325KPa, and so we make P_C the subject of the formula and solve
![P_C= P_T-(P_A+P_B)= 101.33-(38+19)= 101.33-57= 44.3kPa](https://tex.z-dn.net/?f=P_C%3D%20P_T-%28P_A%2BP_B%29%3D%20101.33-%2838%2B19%29%3D%20101.33-57%3D%2044.3kPa)
