Question

Mass of MgCl2: (insert answer)
Mass of NaBr: (insert answer)
Mass of H2O: (insert answer)

Answer 1

To provide you with the mass of MgCl2 (magnesium chloride), NaBr (sodium bromide), and H2O (water), I first need the specific quantities of each compound you are referring to. However, I can give you the molar masses of each compound to help you calculate the mass based on the number of moles or the amount you have.

1. **Molar Masses:**
- **MgCl2 (Magnesium Chloride):**
- Mg: 24.31 g/mol
- Cl: 35.45 g/mol (2 Cl atoms)
- Molar mass of MgCl2 = 24.31 + (35.45 × 2) = 95.21 g/mol

- **NaBr (Sodium Bromide):**
- Na: 22.99 g/mol
- Br: 79.90 g/mol
- Molar mass of NaBr = 22.99 + 79.90 = 102.89 g/mol

- **H2O (Water):**
- H: 1.01 g/mol (2 H atoms)
- O: 16.00 g/mol
- Molar mass of H2O = (1.01 × 2) + 16.00 = 18.02 g/mol

2. **Calculating the Mass:**
If you have specific amounts in moles for each compound, the mass can be calculated using the formula:
\[
\text{Mass (g)} = \text{Number of moles} \times \text{Molar mass (g/mol)}
\]

Please provide the number of moles or other specific details so that I can assist you further with the exact mass values you need!
