Why is the average mass used when calculating grams of a substance?
the elements in the substance are mixtures of their isotopes
How is a mole related to the atomic mass?
The atomic mass, in grams, is the mass of one mole of atoms.
The atomic mass of a mole?
The atomic mass of a mole is equal to the molar mass of that element expressed in grams. It represents the average mass of one mole of atoms of a particular element.
How many grams equal a teaspoon?
On average, a teaspoon of a substance weighs about 5 grams. However, this can vary depending on the density of the substance being measured.
How do you determine the number of moles in an element?
Multiply the # of grams by the element's atomic weight. Or if dealing with milliliters, multiply the volume by solutions molarity. When calculating a molecule's # of moles, multiply the # of grams by the molecular weight.
