1.What is the Density? Mass=121 grams Volume= 11mL:

2.What is the Volume? Mass= 25 grams Density= 5 g/mL:

3.What is the mass? Density= 10g/mL Volume= 50mL:

1. The density is calculated by dividing the mass by the volume. In this case, the mass is 121 grams and the volume is 11 mL. Therefore, the density is 121/11 = 11 g/mL.

2. The volume is calculated by dividing the mass by the density. In this case, the mass is 25 grams and the density is 5 g/mL. Therefore, the volume is 25/5 = 5 mL.

3. The mass is calculated by multiplying the density by the volume. In this case, the density is 10 g/mL and the volume is 50 mL. Therefore, the mass is 10 x 50 = 500 grams.
