In previous tutorials, we calculated the number of moles of a particular compound present in a reaction, including the number of moles of atoms present using the known number of atoms and Avogadro’s number. However, things can get a bit fiddlier when talking about ions. Contents: Examples of Salt Dissociation When a salt is placed … More Moles of Ions in a Solution
The final tutorial in our series on gas stoichiometry will focus on an equation that combines different theories to comprehensively examine the properties of gases. However, we will soon see why this equation isn’t `ideal’ . … More Gas Stoichiometry: The Ideal Gas Law
In the previous tutorial, we examined how to calculate the mass, amount and volume of a gas at standard temperature and pressure (STP). In this tutorial, we are going to calculate the same variables for gases in isolation and as part of a reaction – but at room temperature and pressure (RTP). … More Gas Stoichiometry: RTP
When it comes to working out the mass, amount or volume of a gaseous substance in isolation or in a reaction, you have to consider the properties of temperature and pressure.
The first part of this tutorial on gas stoichiometry will focus on calculating the volume (in dm3 or litres), amount in moles and mass in grams of gaseous substances in isolation or within a reaction at standard temperature and pressure (STP). … More Gas Stoichiometry: STP
In this tutorial, we are going to go through how to calculate the percentage yield and the atom economy of a reaction. … More Percentage Yield and Atom Economy
In this first part of the third tutorial of the trio of tutorials on stoichiometry on this blog, we are going to be going through: what a limiting reactant is and how to identify one in a chemical reaction; how to calculate the amount of product produced using a certain amount of a limiting reactant and how to identify the excess reactant and work out how much excess is left over from a chemical reaction. … More Limiting and Excess Reactants
In this tutorial, we are going to be working out the number of particles – which could be atoms, molecules or formula units – of a substance that are acting as either a reactant or a product of a chemical reaction. … More Determining the Number of Particles of a Reactant or a Product of a Chemical Reaction (with and without Conversion Factors)
In this tutorial, we’ll go over some mole ratio questions while will involve calculating the amount in moles of a reactant or product using the amount in moles of a substance on the other side of a balanced chemical equation.
We are also going to be going over how to calculate the number of particles (atoms, molecules or formula units) that are acting as a reactant or is a product of a chemical reaction. This will be discussed in next tutorial – entitled ‘Determining the Number of Particles of a Reactant or a Product of a Chemical Reaction (with and without Conversion Factors)’. … More Mole Ratio Questions (with and without Conversion Factors)
The following tutorial will cover how to calculate the masses of chemical substances involved in a chemical reaction via stoichiometric calculations using conversion factors to cancel out units. If you would like to see how these calculations can be done without the use of conversion factors to cancel out units, please refer to ‘Determining the … More Determining the Masses of Reactants and Products of a Chemical Reaction (with Conversion Factors)
This is the first part in a series of tutorials on stoichiometry. Stoichiometry is the area of chemistry that involves determining the masses (in grams) and amounts (in moles) of reactants and products of a chemical reaction using a balanced chemical equation.
This tutorial will involve determining the masses in grams of reactants and products of a chemical reaction. This can be done via two methods: one involving cancelling units not needed for an answer with conversion factors and one that doesn’t involve this additional step. … More Determining the Masses of Reactants and Products of a Chemical Reaction (without Conversion Factors)
