Question
Please set up the answer the correct way. I am having a hard time with putting the units in the correct spots.
Transcribed Image Text:### Calculation of Mass in Grams of KBr for a Given Solution
#### Problem Statement:
What is the mass in **grams of KBr** in **0.400 L** of a **0.350 M** solution?
#### Input Section:
- **Starting Amount**: Input fields to enter the initial values. The left input field is for the initial volume in liters (L), and the right input field is for the initial molarity (M).
#### Calculation Section:
- **Add Factor**: Buttons to add factors to the calculation. For example, multiplication (x) and parentheses ( ).
- **Predefined Values**:
- 8.43 × 10²²
- 39.10
- 9.60 × 10^(-3)
- 5.47
- 0.350 (the molarity of the KBr solution)
- 0.140
- 7.09 × 10²⁰
- 16.7
- 1
- 136 (presumably the molar mass of KBr)
- 0.400 (the volume in liters)
- 1.18 × 10^(-3)
- 6.022 × 10²³ (Avogadro's number)
- 119
- **Units**:
- g KBr (grams of KBr)
- mol KBr (moles of KBr)
- L (liters)
- M KBr (molarity of KBr)
- g KBr/mol (grams per mole of KBr)
- mL (milliliters)
#### Output and Reset Section:
- **ANSWER**: Box to show the calculated answer.
- **RESET**: Button to reset the calculation.
### Example Calculation Steps:
1. **Calculate Moles of KBr**:
- Use the formula \( \text{Moles} = \text{Molarity} \times \text{Volume} \)
- Here, \( \text{Moles} = 0.350 \, M \times 0.400 \, L \)
- \( \text{Moles} = 0.140 \, \text{mol KBr} \)
2. **Convert Moles to Grams**:
- Use the molar mass of KBr

Group of answer choices Gently place the pipet bulb on the pipet Keep the tip of the pipet submerged when filling It is best to fill the pipet to a point just above the calibration line, then adjust the volume by slowly releasing liquid. Liquid should fully fill the pipet bulb The more aggressive you are with the pipet bulb, the quicker you will get out of labarrow_forward

You find that the empty container has a mass as 3.05 grams. After obtaining the mass of the empty container you place it beneath the burette and open the stopcock valve. Although you try to stop the flow of liquid B at exactly the 5.00 mL mark you overshoot slightly and end up dispensing 5.14 mL. What is the mass of liquid-B that was dispensed if you continue with the density determination for liquid B and find that the mass of the container plus the 5.14-mL of liquid B is 7.63-grams?arrow_forward
