Question

The density of a substance is 0.87 g/cm3 . Calculate the relative density of the substance. Will this substance float or sink in water? 2 points R.D = 8.7 and it will float R.D = 0.87 and it will sink R.D = 0.87 and it will float R.D = 87 and it will sink
Plz answer​

Answer 1

• Density of substance=0.87g/cm^3=0.087kg/m^3

We know

$\boxed{\sf Relative\:Density=\dfrac{Density\:of\:the\:Substance}{Density\:of\:water\:at\:4°C}}$

$\\ \sf\longmapsto Relative\:Density=\dfrac{0.087kg/m^3}{1000kg/m^3}$

$\\ \sf\longmapsto Relative\:Density=87$

• It will sink in water

Hence Option D is correct.
