Final answer:
The volume of 54 g of water at -1 °C is 54 cm³, calculated using the approximate density of water at 1 g/cm³.
Step-by-step explanation:
To calculate the volume of 54 g of water at − 1 °C, we use the density of water as a conversion factor. The density of water at this temperature is still very close to 1 g/cm³, even though it's just below the freezing point. Thus, for water, the mass in grams approximately equals the volume in milliliters (since 1 cm³ equals 1 mL), and 1 g of water equals 1 cm³ in volume.
The calculation is straightforward:
- Mass of water = 54 g
- Density of water (approximated) = 1 g/cm³
- Volume of water = Mass / Density = 54 g / 1 g/cm³ = 54 cm³
