Final answer:
The mass of the steel block with a volume of 600.0 cm³ and a density of 7.8 g/cm³ is closest to 4. 4700 g, considering rounding to an appropriate number of significant figures.
Step-by-step explanation:
To calculate the mass of a block of steel given its density and volume, we use the formula:
Mass = Density × Volume
Steel has a density of 7.8 g/cm³, and the volume of the block is given as 600.0 cm³.
So the calculation would be:
Mass = 7.8 g/cm³ × 600.0 cm³
Mass = 4680 g
Since this number isn't one of the provided options, we must consider significant figures and rounding. Steel's density might be rounded to a more precise measurement, so the closest provided option that is appropriate for the calculated mass is:
4) 4700 g
