The density of pure gold is 19.3 g/centimeter cube. A quantity of what appears to be gold has a mass of 465 grams and a volume of 26.5 mL. Is the substance likely to be pure gold?
please tell me how you got your answer. Thanks!
density = mass/volume
You know mass is 465 grams.
You know the volume is 26.5 mL or 26.5 cc.
calculate density and compare to 19.3
what is the volume in cm^3 og gold that has a mas of 0.0025kg
8.99
To determine whether the substance is likely to be pure gold, we need to calculate its density and compare it to the known density of pure gold (19.3 g/cm³).
First, we calculate the density of the substance using the formula:
density = mass / volume
We are given that the mass of the substance is 465 grams and the volume is 26.5 mL (or equivalently, 26.5 cm³).
Plugging in these values into the formula:
density = 465 g / 26.5 cm³
Calculating this expression:
density ≈ 17.55 g/cm³
Comparing the calculated density to the known density of pure gold (19.3 g/cm³), we can see that the calculated density is lower than the known density.
Therefore, based on the calculated density, the substance is unlikely to be pure gold.
