Moles are typically used instead of weight or volume in chemistry, because writing chemical equations in terms of moles shows the relationships between the amounts of the reactants and the products, and it is a
Use this information to calculate the stoichiometry of the reaction. (Ar values: Cl = 35.5, Si = 28.1)Significant figures When we perform chemical calculations it is important that we give the answer to the number of significant figures that fits with the data provided. The examples show the...
The calculator below calculates the mass of the substance in grams or the quantity of the substance in moles. Depending on the input data it can serve either as grams to moles calculator or as moles to grams calculator. It also displays the molar mass of the chemical substance and details o...
For example, if you need 8 moles of a substance to carry out a reaction and in your laboratory, you have a 2M solution of that substance, you will need 4 L of the 2M solution to carry out the reaction.Similar Chemistry Calculators Molarity Calculator PPM to mg/L Converter mg/L to...

Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.Using the chemical formula of the compound and the periodic table of elements, we ...
The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation ...
mole. Usually, moles refer to particles that make up a certain amount of an element, and we use moles to measure how much of a substance is reacting in a chemical equation. However, you can also measure other things in moles—for example, a mole of hippos would be 6.02×1023 hippos ....
