The density of pure gold is 19.3g/cm3. What is the volume of 1.00 g of pure gold?
soldier1979 [14.2K]

Answer: Volume of 1g of pure gold v=0.05181 \mathrm{cm}^{3}

Given;

Density of a pure gold=19.3 g / c m^{3}

Mass of a pure gold =1g

To find:

Volume of 1g of pure gold

Solution:

According to the formula,

Density= Mass/Volume

     \rho=m / v

Where \rho=density of pure gold

           m=mass of pure gold

          v=volume of pure gold

From the above equation volume can be calculated as

v=m / \rho

Substitute the values of mass and density value in the above equation

v=1 / 19.3

v=0.05181 \mathrm{cm}^{3}

Result:

Thus the volume of 1g of pure gold is v=0.05181 \mathrm{cm}^{3}
