Composition of any substance, or the element gold (Au) in this example is based on its constituent parts. Pure and elemental Au is 100% by composition. Au alloys measured by carat (24, 22,19) contain other metals to add hardness thus decreasing the precious metal content. 24 carat gold is 99.5% pure for example.
22 carat gold is considered a pure substance because it is composed of a single type of atom, which is gold. It is an alloy of gold and other metals like copper or silver, but it still maintains the properties of gold as a single element.
It is a homogeneous mixture.. NOT a pure element because of the carat gold
No, 18 carat gold is not a pure substance. It is an alloy made of 75% gold and other metals like copper, silver, or palladium.
Fourteen carat gold is a mixture of 58.5% pure gold and 41.5% other metals such as copper, silver, or zinc. This combination of metals makes the gold alloy stronger and more durable than pure gold.
No, a bar of pure gold is not a mixture. It is a pure substance because it is composed of only one type of atom, gold.
18 carat gold is a mixture because it is composed of 75% gold and 25% other metals such as copper or silver.

Fourteen carat gold is a mixture of 58.5% pure gold and 41.5% other metals such as copper, silver, or zinc. This combination of metals makes the gold alloy stronger and more durable than pure gold.
It's an element. So, yes, it's a substance, not a mixture.
No, a bar of pure gold is not a mixture. It is a pure substance because it is composed of only one type of atom, gold.
No, pure gold is not a mixture. It is considered a pure substance because it is composed of only one type of atom, which is gold.
A pure substance is a type of matter that has a constant and specific chemical composition. It is made up of only one type of atom or molecule, with uniform properties throughout. Impurities or additional substances are not present in a pure substance.
Gold is a pure substance
No, gold is an element, not a mixture. It is a pure substance composed of only gold atoms.
