A laboratory technician measures a sample of concentrate using a measuring cylinder.
| Measurement | Value |
|---|---|
| Mass of empty, dry measuring cylinder | 40 g |
| Mass of measuring cylinder and concentrate | 190 g |
| Volume of concentrate | 125 ml |
Which value should the technician record for the density of the concentrate?
1.2 g/cm31.2\ \mathrm{g/cm^3}1.2 g/cm3
1.52 g/cm31.52\ \mathrm{g/cm^3}1.52 g/cm3
0.32 g/cm30.32\ \mathrm{g/cm^3}0.32 g/cm3
0.83 g/cm30.83\ \mathrm{g/cm^3}0.83 g/cm3
