What is pv=nrt

Ideal gas equation, Pressure*Volume=N amount of gas in mol, R is the ideal gas constant and T is the temperature in Kelvin.

What is the Rydburg formula

1/wavelength = R(1/n₁² - 1/n₂²) R is the Rydburg constant and n is the shift in energy levels

How to get wavelength from Frequency

C/V / Speed of light/ frequency

How get Frequency from wavelength

Frequency = C / Wavelength

How to get wavelength from energy

hc/E / (plancs constant*speed of light)/Energy

heat transfer equation

Q=mcΔT where Q is heat transfer, m is mass, c is specific heat capacity, and ΔT is the change in temperature.

Molarity equation

M= Moles of solute / liters of solution

Dilution equation

M₁V₁=M₂V₂

Daltons law of partial pressures

P_total=P₁+P₂….

Ideal gas law (solving for gas constant)

R=(L*atm)/(Mol*K)
