What is gold's atomic mass unit?
The atomic mass of Gold (Au) is 196.9665 grams per mole.
What is the density of gold when the mass is 5.00 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.
Gold is a precious metal with a density of 19.3 grams per ml. If a piece of gold weighs 100 grams what volume in ml should this gold displace in water?
The volume of gold displacing the water can be found using the density formula: density = mass/volume. Rearranging the formula to solve for volume, volume = mass/density. Plugging in the values given, volume = 100 grams / 19.3 grams per ml = 5.18 ml. So, the gold should displace 5.18 ml of water.
How many grams of ice can be melted with 145 grams of 45 degree C H2O?
To calculate how many grams of ice can be melted by 145 grams of water at 45°C, you first need to determine how much heat is required to cool the water to 0°C and then how much heat is needed to melt the ice at 0°C. Use the specific heat capacity of water (4.18 J/g°C) and the heat of fusion of ice (334 J/g) in your calculations. The final result will be the mass of ice melted.

When gold is melted does it weigh less?
No, when gold is melted it does not weigh less. Its mass remains the same, but its volume may change depending on its state (solid or liquid).
How many grams are in 2.8 moles of gold?
The molar mass of gold is approximately 197 grams/mol. To convert moles to grams, you multiply the number of moles by the molar mass. Therefore, 2.8 moles of gold would be approximately 2.8 * 197 = 551.6 grams.
How many grams of gold are there in 15.3 moles of gold?
First look up the atomic mass of gold on the periodic table: Gold, with atomic symbol Au, has an atomic mass of 196.9 grams/mole. Then simply take 15.3 moles of gold and multiply by 196.9 grams/mole to get 3008 grams, which is equal to 3.01 kilograms (kg) gold.
Mass of gold?
The mass of gold is approximately 19.32 grams per cubic centimeter at room temperature.
If a pure gold bar is made up of 19.55 mole of gold what is the mass of the bar in grams?
The molar mass of gold is 196.97 g/mol. Therefore, 19.55 moles of gold would be: 19.55 moles x 196.97 g/mol = 3850.0935 grams So, the mass of the pure gold bar would be approximately 3850.09 grams.
Does melted gold weigh more or less then solid gold?
Melted gold weighs the same as solid gold of the same mass, as weight is dependent on the amount of material present. However, when gold is melted, its volume decreases due to the loss of air pockets and impurities, leading to a higher density and smaller volume.
What is 6 grams of gold is equal to?
6 grams of gold is equal to its weight in grams, which is a measure of mass. In terms of value, the worth of 6 grams of gold would depend on the current market price for gold.
How many grams of gold are in a 10 karat gold necklace with a mass of 28 grams?
To calculate the amount of pure gold in a 10 karat gold necklace, we first need to determine what percentage of the necklace is gold. Since 10 karat gold is 41.7% gold, we can multiply the mass of the necklace by this percentage to find the mass of gold in the necklace. Therefore, in a 28 gram 10 karat gold necklace, there are approximately 11.7 grams of pure gold.
How many grams are in one mole of gold?
Technically, elemental gold does not have a molar mass, because it does not form molecules. For metals and ionically bonded compounds, the proper term is "formula mass", and for gold the formula is considered to be a single atom, resulting a gram atomic mass of 196.967 grams.
What is the mass of 1cm3 of gold and the density of gold is 19.3 gcm3?
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.
What mass does 3.0 ml of gold have?
To find the mass of 3.0 ml of gold, we can use the density of gold, which is approximately 19.32 grams per cubic centimeter (g/cm³). Since 1 ml is equivalent to 1 cm³, the mass can be calculated as follows: mass = density × volume = 19.32 g/cm³ × 3.0 cm³ = 57.96 grams. Therefore, 3.0 ml of gold has a mass of approximately 58 grams.
