Substance
To determine the mole fraction of a substance in a mixture, you divide the moles of the substance by the total moles of all substances in the mixture. This gives you a ratio that represents the proportion of that substance in the mixture.
The amount of each substance in a mixture can change if more of a substance is added or removed, causing the proportions of the substances in the mixture to change. However, the total amount of each substance in the mixture will remain constant.
A solution is a mixture in which a substance dissolves into another substance at the molecular level. The substance that dissolves is called the solute, while the substance it dissolves into is called the solvent. The result is a homogenous mixture with uniform composition throughout.
its not a mixture because i had a test on it and it said it was a pure substance.
The opposite of a pure substance is a mixture.
An element - substance - NOT a mixture.
a mixture is not a substance
a mixture is not a substance
No, it is a mixture; rarely a drug is a pure substance.

It is a mixed substance. ---------------------------------------------- It is a mixture
Ice cream is a mixture.
It would be an mixture
No a mixture is by definition not a pure substance.
Substance
Mole percent, or molar percent of a substance is the ratio of the moles of a substance in a mixture to the moles of the mixture. It represents the number of moles of a substance in a mixture as a percentage of the the total number of moles in the mixture. Mole % = (mol substance in a mixture) / (mol mixture) * 100
