Gas laws are a group of formulas explaining how gases behave under different circumstances in respecting to pressure, temperature, volume and moles.

$P$, Symbol for Pressure(in Atmospheres(1atm = 101325Pa = 760torr));

$V$, Symbol for Volume(in Litres);

$R$, Symbol for Universal Gas Constant(in L atm K^{−1} mol^{−1});

$g$, Symbol for Sample Weight(in grams);

$\mathrm{FW}$, Symbol for Formula Weight(in grams);

${P}_{T}$, Symbol for Total Pressure(in Atmospheres(1atm = 101325Pa = 760torr));

$X$, Symbol for Checked Variable;

Gas laws, Laws that relate the pressure, volume, and temperature of a gas. Boyle’s law—named for Robert Boyle—states that, at constant temperature, the pressure P of a gas varies inversely with its volume V, or PV = k, where k is a constant. Charles’s law—named for J.-A.-C. Charles (1746–1823)—states that, at constant pressure, the volume V of a gas is directly proportional to its absolute (Kelvin) temperature T, or V/T = k. These two laws can be combined to form a single generalization of the behaviour of gases known as an equation of state, PV = nRT, where n is the number of gram-moles of a gas and R is called the universal gas constant. Though this law describes the behaviour of an ideal gas, it closely approximates the behaviour of real gases. See also Joseph Gay-Lussac.

${P}_{1}{V}_{1}={P}_{2}{V}_{2}$

$\frac{{V}_{1}}{{T}_{1}}=\frac{{V}_{2}}{{T}_{2}}$

$\frac{{P}_{1}{V}_{1}}{{T}_{1}}=\frac{{\displaystyle {P}_{2}{V}_{2}}}{{\displaystyle {T}_{2}}}$

$PV=nRT$

$PV=gRT/FW$

- Enter ${n}_{\mathrm{y}}$ values up to 'y' by using comma instead of space.

* If,

* ${n}_{\mathrm{a}}$ = 2

* ${n}_{\mathrm{b}}$ = 1.83

* ${n}_{\mathrm{c}}$ = 3.05

* Enter 'y' = 3;

* ${n}_{\mathrm{y}}$ = 2,1.83,3.05

${P}_{T}=({n}_{a}+{n}_{b}+{n}_{c}+...)RT/V$
