Final answer:
To find the mass of 50cm3 of steel with a density of 7.85g/cm3, you multiply the volume by the density. The mass is 392.5 grams.
Step-by-step explanation:
The question is asking to find the mass of 50cm3 of steel, given the density of the steel is 7.85g/cm3. To calculate the mass, we use the formula Mass = Density × Volume.
Given:
- Density of steel = 7.85g/cm3
- Volume of steel = 50cm3
The mass of the steel can be calculated as follows:
Mass = Density × Volume
= 7.85g/cm3 × 50cm3
= 392.5g
Therefore, the mass of 50cm3 of steel is 392.5 grams.
