For the volume of a solid or liquid
Density = mass/ volume so
volume = mass / density
For the volume of a liquid
Moles = volume x concentration
Volume = moles / concentration
For the volume of a gas
Volume = moles x 24
There are many other formulas as well :)
The rms speed of a gas can be calculated using the following rule:
Vrms = sqrt[(3RT) / M] where
R is the gas constant = 8.314 <span>J K^−1 mol^−1
T is the temperature = 32.5 + 273 = 305.5 degree kelvin
M is the molar mass = 2*14 = 28 grams = 0.028 kg
Substitute with the givens in the equation to get the rms speed as follows:
Vrms = sqrt [(3*8.314*305.5) / 0.028]
Vrms = 521.665 m/sec</span>
<span>Protons and neutrons are both centrally located in an atom's nucleus, while negative electrons surround the nucleus in designated shells (which are commonly thought of as "orbits" as labeled in the PhET simulation).
Nucleus of an atom has positive charge, electrons are negative and atom has neutral net charge.</span>
