Which substance has the greatest density aluminum iron water gold wood or ice?
Look at the Periodic Table the higher the Atomic Number the greater the density.Unless you are talking about air consisting of mostly Radon gas, Gold has the greatest density with an atomic weight of 196 compared to Aluminum's 27. and obviously normal air and ice are not even close to as dense.so the answer is most likely C. Gold
What is oxidation in a galvanic cell with aluminum and gold electrodes?
The aluminum metals
What is the volume for a mass of 9.5 grams?
It depends on the density of the material. You must know, or be able to determine, the density of what you're measuring in order to determine the volume occupied by 9.5 grams of it. Density = mass divided by volume. So, volume = mass divided by density. For example, the volume of 9.5 grams of gold or lead is less than the volume of 9.5 grams of aluminum -- because gold and lead both have a higher density than aluminum does. (Logical, since a bucket filled with lead is a lot harder to lift than a bucket filled with aluminum.) For reference, the volume of 9.5 grams of water (at a standard temperature, pressure, etc.) is 9.5 ml. or 9.5 cc. (1 ml. or millilitre equals 1 cc. or cubic centimetre; both being the volume of a cube with sides measuring one centimetre.) The volume of 9.5 grams of any solid, liquid, or gas, is inversely proportional to the density, and can be compared to the volume and density of water. (For example, 9.5 grams of a material that's 9.5 times denser than water would occupy a volume of 1 ml. or 1 cc.) For a material of unknown density, you can determine its density by submerging a known mass of it in water, and measuring the volume (hence, the mass) of water it displaces. That's known as Archimedes Principle. Archimedes wanted to know if an object was pure gold (with a known density), or if it was gold mixed with a cheaper metal (with an unknown density). That's why Archimedes was motivated to be able to determine the density of an unknown material. For any material of known density, just look up its density, then calculate its volume using the formula above (volume = mass divided by density).
Why can't we use aluminum for melting gold?
Because aluminum has a melting point of 933.47K and gold has a melting point of 1337.33K thus, the aluminum would melt BEFORE the gold.
Why is gold found as gold metal but aluminium is found as aluminium oxide?
Gold is a very unreactive element, so it occurs as gold metal in nature. However, aluminum is more reactive, and so it occurs in aluminum ore (aluminum oxide) in nature, not as aluminum metal.

Why does a kilogram of aluminum have more volume than a kilogram of gold?
Aluminum has a low density so it takes more to make a kg
Why density be used to separate gold from surrounding material?
Because gold is one of the heaviest elements
a scientist has a sample of a substance with a volume of 50cm cubed and a mass of 135g. this is most likely a sample og which substance gold, pure water, aluminum or ocean water?
The **density** of a substance is defined as its mass per unit volume. We can calculate the density using the formula: [ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} ] Given that the sample has a volume of **50 cm³** and a mass of **135 g**, let's determine the density: [ \rho = \frac{135 , \text{g}}{50 , \text{cm³}} ] The calculated density is approximately **2.7 g/cm³**[^10^]. Now let's compare this value to known densities: **Gold**: Gold has a density of *19.3 g/cm³*⁷. The sample's density is significantly lower. **Pure Water**: The density of pure water is approximately **1 g/cm³** at 4.0°C (39.2°F) . The sample's density is higher than water. **Aluminum**: Aluminum has a density of *2.7 g/cm³*[^10^]. The sample's density matches that of aluminum. **Ocean Water**: Ocean water contains dissolved salts, which increase its density. Seawater density typically ranges from *1.02 g/cm³ to 1.03 g/cm³*. The sample's density is higher than seawater. Based on the calculated density, the sample is most likely **aluminum**.
What is the density of gold alloys compared with the carat rating of the alloy?
There is not any simple relationship between density of an alloy and its gold contents. Consequently a measurement af a gold bullion`s density is not used for assaying the gold contents. Pure gold having a density of 18,3 can be alloyed with Platinum(more expensive) to raise density of the ingot above 20. It may also be alloyed with aluminum (God forbid) to bring down the density.
Does gold or lead have a higher density?
it actually gold because Lead has a density of about 11.3 grams per cc, Gold has a density of about 19.3 grams per cc, so for a given volume, gold is much heavier than lead.
Is gold less than water?
Gold sinks when you place it in water. So, gold has a higher density than water.
What has a higher density a small pure gold ring or a large pure gold ring?
I think it is the large gold ring
Can gold float on mercury?
Gold is a higher density than Mercury so it will sink if placed into a container of mercury.
