Science is the process by which we learn about the natural universe by observing, testing, and then generating models that explain our observations. This includes advances in medicine, communication, transportation, building infrastructure, food science and agriculture, and nearly every other technical field that you can imagine.Ĭhemistry is one branch of science. From the color that makes a rose so red to the gasoline that fills our cars and the silicon chips that power our computers and cell phones…Chemistry is everywhere! Understanding how chemical molecules form and interact to create complex structures enables us to harness the power of chemistry and use it, just like a toolbox, to create many of the modern advances that we see today. Section 2.1: Chemistry and Matter What is Chemistry?Įverything around us is made up of chemicals. You might wanna check out our Gay-Lussac's law calculator.Chapter 2: Atoms and the Periodic Table Section 2.1: Chemistry and Matter What is Chemistry?

So how about giving the Boyle's law calculator a try?Ĭharles's law – The formula used when dealing with an isobaric process (a process where the pressure does not change): Try to keep your notes as simple as possible!īoyle's law – The formula used when dealing with an isothermal process (a process where the temperature does not change): Depending on the process, you may also cross out one of the following variables: T, V, P. (R is equal to the Avogadro's constant multiplied by the Boltzmann constant)Īlways remember that the nR part of any of these equations is constant – it means it may be crossed out when you transform the formula. R – The ideal gas constant = 8.314 J/(mol With just a few transformations, we can use this formula to determine all the properties of a given gas in three types of processes: isobaric, isochoric, and isothermal.īelow you will find all of the most essential, ready-to-go equations used in all those calculations, along with a quick explanation. That's why we use the combined gas law calculator (a.k.a. There are plenty of chemistry-based queries that can be solved by some form of the original ideal gas law. The molar mass of gas is not the only thing we can calculate with the ideal gas law! A Dalton is a unit of atomic mass equal to the mass of 1/12 of a particle of carbon ¹☬.
The calculated value is numerically identical to 1 u (or 1 Da = Dalton, used in biochemistry). It's as simple as that! Recommended units:īut your mass isn't given in grams? Don't worry why don't you take some time to discover how to properly convert between different densities and weights? If you want to work it out yourself, without the molar mass of gas calculator, be careful with the units! This particular equation uses a constant of 0.0821, which is intended for the following units: Moles = (Pressure × Volume) / (0.0821 × Temperature) Our gas law calculator uses the following equations:
You need the following data about the gas:
