The density of the box of sand is 30 grams per cubic centimeter (g/cm3). This is calculated by dividing the mass (6000 grams) by the volume (200 cm3).
To find the density, divide the mass of the rock (15 grams) by its volume (30 milliliters). Density = mass/volume, so in this case 15 grams / 30 milliliters = 0.5 grams per milliliter. Therefore, the density of the rock is 0.5 g/mL.
The density of zinc is approximately 7.14 g/cm³. To calculate the volume of zinc, divide the mass (213g) by the density of zinc (7.14 g/cm³). The volume of zinc would be approximately 29.83 cm³.
There are 20 cubic centimeters (cm3) in 20 milliliters (mL) since they are equivalent volume units.
mass= density *volume Density of copper= 8.94g/cm3 so mass =8.94g/cm3 * 10cm3= 89.4g
