Reference no: EM133886

Question1

1) The molecular mass of helium is 4 g/mol, Boltzmann’s constant is 1.38066 × 10−23 J/K, universal gas constant is 8.31451 J/K mol, and Avogadro’s number is 6.02214 × 1023 1/mol. Given: 1 atm = 101300 Pa. How many atoms of helium gas are necessary to fill a balloon to diameter 25 cm at 59?C and 0.934 atm?

2) What is average kinetic energy of each helium atom? Answer in units of J

3) what is rms speed of each helium atom? Answer in units of m/s

Question2

A rod of length 30.0cm has linear density given by =50.0+20.0x,where x is distance from one end, measured in meters and linear density is in grams/meter.

a) What is the mass of the rod?

b) How far from the x=0 end is its center of mass?
