2.00 mol of the helium is confined to a 2.00-L container at a pressure of 11.0 atm. The atomic mass of helium is 4.00 u, and the conversion between u and kg is 1 u = 1.661 ××10−27 kg. 1)Calculate vrms

use P*V = n*R*T

==> T = P*V/(n*R)

= 11*1.013*10^5*2*10^-3/(2*8.314)

= 134 k

we know,

v_rms = sqrt(3*k*T/m)

v_rms = sqrt(3*1.38*10^-23*134/(4*1.66*10^-27))

= 914 m/s  

The root-mean square (RMS) velocity is the cost of the square root of the sum of the squares of the stacking speed values divided via the variety of values. The RMS pace is that of a wave via sub-floor layers of different c programming language velocities along a selected ray route.

The rms speed is at once proportional to the square root of temperature and inversely proportional to the rectangular root of molar mass. for this reason quadrupling the temperature of a given gas doubles the rms pace of the molecules.

Helium is a chemical element with symbol He and atomic number.

It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first gas in the noble gas group of the periodic table.

Its boiling point and melting point are the lowest of all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant).

Helium is used as a coolant for the Large Hadron Collider (LHC) and superconducting magnets in MRI scanners and NMR spectrometers. It is also used to cool satellite instruments and is used to cool the liquid oxygen and hydrogen that power the Apollo spacecraft.
