Complete the following sentences:
(i) Mass = ………..`xx` density

Answer

To complete the sentence "Mass = ………..`xx` density", we can follow these steps:

1. **Understand the relationship between mass, volume, and density**:
- Density (ρ) is defined as mass (m) per unit volume (V). The formula for density is:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \quad \text{or} \quad \rho = \frac{m}{V} \]

2. **Rearrange the formula to find mass**:
- To find mass in terms of density and volume, we can rearrange the formula:
\[ \text{Mass} = \text{Density} \times \text{Volume} \quad \text{or} \quad m = \rho \times V \]

3. **Identify the missing term in the sentence**:
- From the rearranged formula, we see that mass is equal to density multiplied by volume. Therefore, the missing term in the sentence is "volume".

4. **Complete the sentence**:
- The completed sentence is:
\[ \text{Mass} = \text{Volume} \times \text{Density} \]

### Final Answer:
Mass = Volume `xx` density
