Gold colored ring has a mass of 18.9 grams and a volume of 1.12 ml. Is the ring pure gold (The density of gold is 19.3 gml.) Explain.?

To determine if the ring is pure gold, we can calculate its density using the formula Density = Mass/Volume. The calculated density of the ring is approximately 16.9 g/ml, which is lower than the density of pure gold (19.3 g/ml). Therefore, the ring is not made of pure gold, as its density does not match the density of pure gold.
