Answer: 169ml
Explanation
At constant temperature, PV is constant
Standard pressure is 101 kpa
150ml X 114kpa=?mlX101 kpa
?=114/101 X150 = 169 ml
Answer:
13.5 %
Explanation:
First we<u> calculate the mass of 500 mL of water</u>, using <em>its density</em>:
- 500 mL * 1.00 g/mL = 500 g
Then we <u>calculate the mass percent of potassium sulfate</u>, using the formula:
Mass of Potassium Sulfate / Total Mass * 100%
- 78 g / (78 + 500) g * 100 % = 13.5 %
Uhh...

Answer:
2.5 moles
Explanation:
Number of moles = MassMolar mass
= 80⋅g32.06⋅g⋅mol−1 = ??mol
Note that sulfur likely exists in its elemental state as S8. I am perfectly justified in treating sulfur as S. The number of sulfur atoms is the same in each case.
