Prism Molarity Calculator
What is the Promotion Calculator?
The Promotion Calculator is designed for employees, HR professionals, and managers who want to quickly calculate the updated salary after a raise or promotion.
Instead of manually using formulas, this tool does the work for you in seconds.
Formula used: New Salary=Current Salary+(Current Salary×Promotion Increase %100)\text{New Salary} = \text{Current Salary} + \left(\text{Current Salary} \times \frac{\text{Promotion Increase \%}}{100}\right)New Salary=Current Salary+(Current Salary×100Promotion Increase %)
How to Use the Promotion Calculator
- Enter your current salary in the input box.
- Enter the promotion increase percentage (e.g., 10 for 10%).
- Click “Calculate” to see your new salary.
- If needed, click “Reset” to clear values.
Example of Promotion Calculation
- Current Salary: $50,000
- Promotion Increase: 15%
50,000+(50,000×15100)=50,000+7,500=57,50050,000 + (50,000 \times \frac{15}{100}) = 50,000 + 7,500 = 57,50050,000+(50,000×10015)=50,000+7,500=57,500
✅ New Salary = $57,500
This tool instantly gives you the result, avoiding manual errors.
What is the Prism Molarity Calculator?
The Prism Molarity Calculator helps chemistry students and professionals calculate the molarity of a solution, which is the concentration of solute (in moles) per liter of solution.
Formula used: Molarity (M)=Moles of SoluteVolume of Solution (L)\text{Molarity (M)} = \frac{\text{Moles of Solute}}{\text{Volume of Solution (L)}}Molarity (M)=Volume of Solution (L)Moles of Solute
How to Use the Molarity Calculator
- Enter the moles of solute in the first box.
- Enter the volume of solution (in liters) in the second box.
- Click “Calculate” to get the molarity value.
- Click “Reset” to clear inputs.
Example of Molarity Calculation
- Moles of Solute: 0.25 mol
- Volume of Solution: 0.5 L
M=0.250.5=0.5MM = \frac{0.25}{0.5} = 0.5 MM=0.50.25=0.5M
✅ Molarity = 0.5000 M
This is useful for chemistry labs, assignments, and professional research.
