75.0 degrees Celsius = 75.0 + 273 = 348 K.
Assuming pressure is held constant,
Answer:
- <u><em>Option A.) 2 ppm</em></u>
Explanation:
<u><em>60 particles in 30 million</em></u> can be expressed as a fraction:
And, dividing both numerator and denominator by 30, that can be simplified as:
That means 2 particles of sulfur dioxide in 1 million particles of sample, which is 2 parts per million or<u> 2 ppm</u>, which is the option A.
1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution. Details about molarity can be found below.
<h3>How to calculate molarity?</h3>
The number of moles of a solution can be calculated by multiplying the molarity of the solution by its volume. That is;
no of moles = molarity × volume
According to this question, a solution has a molarity of 8.20M and volume of 125 mL of solution.
no of moles = 8.20 × 0.125
no of moles = 1.025moles
Therefore, 1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution.

Answer:
Warm water has more energy than cold water. The more energy the more the water molecules move around pushing the food coloring. Think gas—liquid is evaporated because of heat and the molecules move more than in a liquid state.
