How many moles of Li3N will be created using 0.24 moles of Li in the given reaction? 6Li + N2 2Li3N 0.04 moles 0.08 moles 0.12 m
Damm [24]
6 Li + N2 = 2 Li3N

6 moles Li ------------ 2 moles Li3N
0.24 moles Li ------- moles Li3N

moles Li3N = 0.24 *2 / 6

moles Li3N = 0.48 / 6 => 0.08 moles

The vapor pressure of pure acetone is 266 torr. When a non-volatile solute is added, the vapor pressure of acetone above the sol
mixas84 [53]

Answer : The mole fraction of the non-volatile solute in the solution is 0.195

Explanation :

According to the relative lowering of vapor pressure, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component of the solution multiplied by the vapor pressure of that component in the pure state.

Formula used :

\frac{\Delta p}{p^o}=X_B

\frac{p^o-p_s}{p^o}=X_B

where,

p^o = vapor pressure of the pure solvent (acetone)  = 266 torr

p_s = vapor pressure of the solution = 214 torr

X_B = mole fraction of solute  = ?

Now put all the given values in the above formula, we get:

\frac{p^o-p_s}{p^o}=X_B

\frac{266-214}{266}=X_B

X_B=0.195

Therefore, the mole fraction of the non-volatile solute in the solution is 0.195
