Answer:
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Wavelength = 515 nm
Also, 1 m = nm
So,
Wavelength = m
Thus, Frequency is:

Answer:</h3>
2703 moles
<h3>
Explanation:</h3>
<u>We are given</u>;
- The equation for the reaction;
C₃H₈(g) + 5O₂ (g) → 3CO₂ (g) + 4H₂O (g)
- Moles of C₃H₈ are 901 moles
We are required to calculate the number of moles of CO₂ formed.
- From the equation, 1 mole of propane reacts with 5 moles of oxygen to form 3 moles of CO₂ and 4 moles of water.
- Therefore, the mole ratio of C₃H₈ to CO₂ is 1 : 3
Thus; moles of CO₂ = Moles of C₃H₈ × 3
= 901 moles × 3
= 2703 moles
Thus, moles of CO₂ formed will be 2703 moles
211.07 mL of water must be added to 25.00 mL of a 0.1000 M sugar solution to make 0.01059M solution.
HOW TO CALCULATE CONCENTRATION:
- The concentration of a solution can be calculated by using the following formula:
C1V1 = C2V2
Where;
- C1 = initial concentration (0.100M)
- C2 = final concentration (0.01059M)
- V1 = initial volume (25mL)
- V2 = final volume (mL)
- 0.100 × 25 = 0.01059 × V2
- Therefore, the amount of water added to the sugar solution is 236.07 - 25 = 211.07mL.
