the density of mercury is 13.3 g cm-3. what is its D in kg m-3 and standard form?

12-6m

13.3 g/cm^3 * (100cm/m)^3 (1kg/1000g)=

13.3E3 kg/m^3=1.3^10^4 kg/m^3

To calculate the density of mercury in kg/m^3, you need to convert grams to kilograms and centimeters to meters.

Given: Density of mercury = 13.3 g/cm^3

Step 1: Convert grams to kilograms.
Since there are 1000 grams in a kilogram, you divide the density by 1000.
Density in kg/m^3 = 13.3 g/cm^3 / 1000 = 0.0133 kg/cm^3.

Step 2: Convert cubic centimeters to cubic meters.
Since there are 1,000,000 cubic centimeters (cm^3) in a cubic meter (m^3), you divide the density by 1,000,000.
Density in kg/m^3 = 0.0133 kg/cm^3 / 1,000,000 = 1.33 × 10^-5 kg/m^3.

In standard form, the density of mercury in kg/m^3 is 1.33 × 10^-5 kg/m^3.
