Concept: Relative density (also known as specific gravity) of a substance is the ratio of its density to the density of a reference substance, which is usually water at .
Relative Density ( ) = .
Therefore, Density of substance = Relative Density Density of water. Step 1: Identify the given values
Relative density of silver ( ) = 10.8 (This is a dimensionless quantity).
Density of water ( ) = (which is ). We need to find the density of silver ( ). Step 2: Use the formula relating density, relative density, and density of water
Step 3: Substitute the given values and calculate
The density of silver is . Step 4: Compare with the options
(1) : This matches our calculated value and has the correct units.
(2) : The numerical part might seem similar, but the unit is . The density of water in is . If we used that, density of silver would be . The value is incorrect.
(3) : Incorrect magnitude.
(4) : Incorrect magnitude. The correct density of silver is .
