Answer:
a. Dew point: 48.7°C. Degrees of superheat 26.3°C
b. 
c. 
Explanation:
a. Based on the psychometric chart of air, the specific volume of air at the given conditions is:
The dew point at the specific volume and the 30%-humidity has a value of 48.7°C, it means that there are 75°C-48.7°C=26.3°C of superheat.
b. At 75°C the molar fraction of water is 11580Pa/101625Pa=0.114 moles per cubic meter of feed gas are:
Once the 35°C are reached, the mole fraction of water is 1688Pa/101325Pa=0.017 and remaining moles per cubic meter of feed gas are:
So the condensed moles per cubic meter of feed gas are:
c. Considering the Raoult's law, one computes the pressure as follows:
At 75°C and 30%-humidity, the saturation water vapor pressure has a value of 38599Pa, thus:

Answer: Blue liquid density = 45 grams/70 mL Density = .64 g/mL Yellow liquid density = 80 grams/ 65mL Density = 1.23 g/mL After the liquids are combined the blue less dense liquid will rise to the top, while the yellow more dense liquid will sinks to the bottom.
Answer:
490. g H₂SO₄
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
<u>Step 1: Define</u>
3.01 × 10²⁴ molecules H₂SO₄
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of H - 1.01 g/mol
Molar Mass of S - 32.07 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂SO₄ - 2(1.01) + 32.07 + 4(16.00) = 98.09 g/mol
<u>Step 3: Convert</u>
<u />
= 490.287 g H₂SO₄
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
490.287 g H₂SO₄ ≈ 490. g H₂SO₄
