Example 10.7 Relative density of silver is 10.8. The density of water is 103 kg m–3. What is the density of silver in SI unit? Given Relative density of silver = 10.8 Density of water = 103 kg/m3 We know that Relative density of silver = (𝐷𝑒𝑛𝑠𝑖𝑡𝑦 𝑜𝑓 𝑠𝑖𝑙𝑣𝑒𝑟)/(𝐷𝑒𝑛𝑠𝑖𝑡𝑦 𝑜𝑓 𝑤𝑎𝑡𝑒𝑟) ∴ 10.8 = (𝐷𝑒𝑛𝑠𝑖𝑡𝑦 𝑜𝑓 𝑠𝑖𝑙𝑣𝑒𝑟)/〖10〗^3 10.8 × 103 = Density of silver Density of silver = 10.8 × 103 kg/m3
