Please help???

Answer 1

Density is mass/volume

1) density = 57 g / 125 cm^3 = 0.446 g/cc

2) is the same, just use the definition and calculate

3) Milliliter is 1/1000 of a liter so multiply or divide by that number as appropriate

4) Use the conversion in 3 to figure this out.  0.25 liters /(1 liter/1000 ml) = 250 ml

Answer 2

1. 0.446 g/cc

2. Same thing

3. 1ml = 1/1000 of a Litre

4. 250 Ml
