How do you know if a half dollar California gold coin is real?
The best test is density, since a fake coin can still have a real gold plating over a base metal interior. Gold is denser than any other commonly available metal (there are denser metals but they are even more expensive than gold, so they would never be used to create counterfeit gold coins). You can measure the weight of the coin on a scale, and the volume can be determined with the use of a graduated cylinder (to measure how much water it displaces) then you can calculate the density, which is simply weight divided by volume. Compare this to the density of gold. If it's pure gold, the coin is real.
How much does the gold coin weigh?

How do you found out if gold is fake?
you could do a density test. If you measure the mass of the object and divide it by the volume (displacement test would be easiest) then you have calculated the density. the density of gold is 19.3 so if you get something close to this then it is gold.
How can density be used to decide if a ring is gold or just gold plated?
Measure the gold, take the volume of the gold, then divide mass over volume to give you the density of gold if it was the same as gold density then it is right other wise that ring is doggy

Estimate the number of gold atoms in a gold coin with a diameter of 1 cm and a thickness of 1mm?
A gold coin with a diameter of 1 centimeter and a 1 mm thickness has a volume of .07854 cubic centimeters. Gold has a density of 19.30 grams per cubic centimeter. There is 1.5158 grams of gold or 7.7 millimoles or 4.637 E21 atoms.
Why would you want to find volume of any object?
If you want to determine the density of an object, you would measure the mass and volume, then divide mass/volume to determine density. This can help determine the composition of the object. For example, if you find a rock that looks like a gold nugget. The density of gold is a known value, so one of the tests in determining if you are holding real gold would be to determine the density of your rock. This is one example. Another (maybe more 'real world' for you). Shipping and cargo companies measure the volume of packages as they go by on the conveyor belt, so that they can figure how many will fit in a particular truck.

How much does a gallon of gold weigh?
A gallon is a measure of volume used for liquids. Gold is not normally not measured by volume but by weight. A troy ounce of gold would have a volume of 1.61 cm3. cm3 = 0.00026417205 gallons 3785.41 cm3 = 1 gallon Therefore, a gallon of gold would weigh 2351.19 troy ounces. Or: gold weighs 19.32 grams/cm3 a gallon is 3,785.612 cm3 3,785.612 cm3 * 19.32 g/cm3 = 73,062.3 grams or 73.06 kg 73.06 kg * 2.2 lb/kg = 161 lb
