The mass of NaCl that reacted with F2 at 290. K and 1.5 atm is 46.75 g. (STP)
What is the mole concept?
The amount of the substance contains an identical variety of discrete entities (atoms, molecules, ions as there are atoms in a sample of pure 12C weighing exactly 12g. In one mole of any substance =Avogadro wide variety=6.022 * 10²³.
F₂ + NaCl = cl₂+ NaF
vol = 18l
pressure = 1.5 atm
temp = 290 l
r = 0.08205 atm/mol k
PV =nrt
⇒1.5*18 = n8 0.08205
N = 1.13 mole
mole = [tex]\frac{mass}{molar mass}[/tex]
mass= 1.13 * 58.94 = 66.03 gram.
P1V1/N1T1 = P2V2/N2T2
⇒ 1.5 * 18/290 * 1.13 = 1* 18 /273*N
⇒ N = 1 * 290 8 1.13/273 *1.5
n = 327.7/409
n = 0.8 mole
Mass = 0.8 * 58.44 = 46.75 g answer.
