A shiny gold colored car of metal weighting 57.3g has a volumes of 4.7cm^3. Is the bar of metal pure gold?

Compare the density of this car with the density of gold.

To determine if the bar of metal is pure gold or not, we can use the density of gold and compare it with the measured density of the bar. The density of a substance is defined as its mass per unit volume.

To find the density of the gold bar, we can use the formula:

Density = mass / volume

Given:
Mass of the metal bar = 57.3g
Volume of the metal bar = 4.7cm^3

Now we can substitute these values into the formula to calculate the density of the bar:

Density = 57.3g / 4.7cm^3

Calculating this gives us the density of the bar.

Next, we can compare this density with the known density of gold, which is approximately 19.3 g/cm^3. If the calculated density of the bar matches the density of gold, then it indicates that the bar is made of pure gold.

So, to answer your question, compare the calculated density of the metal bar with the known density of gold (19.3 g/cm^3). If they match, then the bar is made of pure gold.
