The initial temperature of a sample of chlorine gas is 240 K at a pressure of 6.0 atm. If the temperature is increased to 300. K, what is the final pressure?
Group of answer choices

9.6 atm

7.5 atm

15 atm

4.8 atm

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
