The mass of the 1.2 cm gold cube is (19.32 x 1.2) = 23.184 g
113 divided by 2.5 which is 45.2 inches

One cubic centimeter of gold has more mass than 2 cubic centimeters of copper. Gold has a density of 19.3 grams per cubic centimeter, while copper has a density of 8.94 grams per cubic centimeter so, two cubic centimeters of copper has mass of 17.9 grams, which is less than 19.3 grams of gold.
To find the mass of the platinum disk, use the formula: mass = density * volume. Given the density of platinum is 21.4 g/cm³ and the volume is 113 cm³, the mass can be calculated as 21.4 g/cm³ * 113 cm³ = 2418.2 g. Therefore, the mass of the pure platinum disk would be 2418.2 grams.
The mass of 1 cm^3 of gold is 19.3 grams because density is mass per unit volume. In this case, the density of gold is given as 19.3 g/cm^3, so for 1 cm^3 of gold, the mass would be 19.3 grams.
The mass of the 1.2 cm gold cube is (19.32 x 1.2) = 23.184 g
The density of the gold nugget is 19.3 g/cm^3. This was calculated by dividing the mass (965 g) by the volume (50 cm^3).
The volume of the gold cube is calculated as side cubed (4 cm * 4 cm * 4 cm) = 64 cm^3. Density is mass divided by volume (1235 g / 64 cm^3 ≈ 19.3 g/cm^3). So, the density of the gold cube is approximately 19.3 g/cm^3.
1 inch equals 2.54 cm. Therefore, 113 in = 113 in * (2.54 cm/in) = 287.02 cm.
To determine if the crown is pure gold, calculate its density using the formula density = mass/volume. Substituting the values given, the crown's density should be 1800 g / 110 cm^3 = 16.36 g/cm^3. Since the density of gold is 19.3 g/cm^3, the crown is not made of pure gold as its density is lower than that of gold.
The volume of the gold sample is 5.00 cm^3 and the mass is 96.5 g. Density is calculated as mass/volume, so density = 96.5 g / 5.00 cm^3 = 19.3 g/cm^3.
113 ÷ 10 = 11.3 cm
The density of gold is approximately 19.32 grams per cubic centimeter. To calculate the density when the mass is 5.00 grams, you would need to know the volume of gold. Without the volume, the density cannot be determined.
To calculate the mass of the gold bar, we first calculate its volume using the formula: Volume = length x width x height. With the dimensions provided, the volume is 20.0 cm x 6.0 cm x 1.0 cm = 120 cm³. Next, we multiply the volume by the density of gold to find the mass: 120 cm³ x 19.3 g/cm³ = 2316 grams. Therefore, a gold bar with dimensions 20.0 cm x 6.0 cm x 1.0 cm would weigh 2316 grams.
