Answer:

Let's just say 5 million million hydrogen atoms could fit at the end of a needle.

Explanation:

Atoms are 100 picometers, and to compare, the amount of even 1 centimeter, a calculator can't even figure out how many picometers are in a centimeter because there is just too much picometers.

The ideal gas constant, R has several different values that could be used. Which quantity causes these differences? pressure tem
Blababa [14]

Answer : The correct option is, pressure.

Explanation :

The ideal gas equation is,

PV=nRT

where,

P = pressure of the gas

V = volume of the gas

n = number of moles of gas

T = temperature of the gas

R = gas constant

The value of 'R' has several different values which are :

R=0.08205L.atm/mol.K

R=8.3145L.kPa/mol.K

R=8.3145J/mol.K 

R=1.987cal/mol.K

R=0.08314L.bar/mol.K

That means, the value of 'R' is different due the change in the pressure value and all the variables (temperature, volume and moles) are constant.

Hence, the correct option is, pressure.
