Final answer:
The mass of a substance with a density of 6 g/mL and a volume of 42 mL is 252 g.
Step-by-step explanation:
If the density is 6 g/mL and the volume is 42 mL, we can find the mass by using the formula Density = Mass / Volume. To find the mass, we rearrange this formula to Mass = Density * Volume.
Mass = 6 g/mL * 42 mL
Mass = 252 g
Therefore, the mass is equal to 6 g/mL * 42 mL, which gives us a mass of 252 g.
So, the mass is 252 grams.
