Find the density of a rock that has a mass of 18 g and when dropped into 50mL of water, causes the water to rise to the 67mL mark

67-50=17ml volume d=m/v=18g/17 ml=1.06g/ml if sig figs 1.1g/ml

1.056 g/mL

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL, kg/L

Formula:

D=m/v

D = density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given dа ta:

density=?

volume of water = 50 mL

volume of water + rock = 67 mL

mass = 18 g

first of all we will calculate the volume of rock.

volume of rock = volume of (water + rock) - volume of water

volume of rock = 67 mL - 50 mL

volume of rock = 17 mL

Now we will put the values in the formula,

d = m/v

d = 18 g / 17 mL

d = 1.056 g/mL

The density of rock is 1.056 g/mL
