1.3 Reacting masses and volumes
• Reactants can be either limiting or excess.
• The experimental yield can be different from the theoretical yield.
• Avogadro’s law enables the mole ratio of reacting gases to be determined from volumes of the gases.
• The molar volume of an ideal gas is a constant at specified temperature and pressure.
• The molar concentration of a solution is determined by the amount of solute and the volume of solution.
• A standard solution is one of known concentration.
• Solution of problems relating to reacting quantities, limiting and excess reactants, theoretical, experimental and percentage yields.
• Calculation of reacting volumes of gases using Avogadro’s law.
• Solution of problems and analysis of graphs involving the relationship between temperature, pressure and volume for a fixed mass of an ideal gas.
• Solution of problems relating to the ideal gas equation.
• Explanation of the deviation of real gases from ideal behaviour at low temperature and high pressure.
• Obtaining and using experimental values to calculate the molar mass of a gas from the ideal gas equation.
• Solution of problems involving molar concentration, amount of solute and volume of solution.
• Use of the experimental method of titration to calculate the concentration of a solution by reference to a standard solution.

You probably hear this a lot but you really need to slow down, the content is amazing but it gets really annoying when I have to pause and rewind all the time

[falakshah]

Your videos are AWESOME!!!
But you are fast
even if i pause the videos at the question solving part i have to watch it 3 to 4 times.

[jasonderulo]

You did a mistake while finding the limiting reactantyou forgot to balance the that should be the balanced equation

[jwilliamson]

Your videos have saved my chem mark! Thank you so Much!

[IndianCowboy.]

Your videos are great!! BUT TAKE IT SLOW!!!!

[salls]

Everyone’s saying you’re too fast meanwhile I’m watching this on 1.5x speed lmao

[TW-oguk]

Why didn’t you balance the equation for the first limiting reactant question ?

[chaloratanahall]

Isn't the volume in the equation PV=nRT measured in L, and therefore in dm^3? Why have you been using m^3?

[rfarightforanimals]

Hi your videos are amazing but maybe go a little slow with calculations it’s hard to cope up with the audio and the speed

[nicolemg]

Hi. I have a question regarding the last exercise. Why did you put on the solution the same number of moles of NaOH for the acid (0.0025 mol), if the ratio NaOH:H2SO4 was 1:2?

[schenzur]

Although these vids are reviews, they are great for clearing out the concepts.

[elizasteinberg]

I love your videos! I've learned that 1 mole of gas at STP = 22.4 L though?

[hakimihkm]

Hey for the titration questions what was the difference between problem 1 and problem 2? Why can't we use c1v1=c2v2 in problem 2 like u did in problem 1?

[anshumansingh]

This videos are So much chemistry, I love it!

[isabellelightwood]

how did you obtain the concentration of co2

[chroniszaf]

Bro its extremely fast, especially the exercises. Even rewinding doesnt help cause they are explained synoptically.

[naysa]

I'm watching this a year later and I still don't get percentage yield :(
