How many grams of NaOH are produced from 1.20 x 10^2 of Na2O
oksian1 [2.3K]
Write an balance the equation

Na2O + H2O -> 2 NaOH

Calculate the molecular mass of Na2O and NaOH from the atomic mass from the periodic table.

Na = 23
O=16
H=1

Na2O = 23 * 2 + 16 = 62
NaOH = 23+16+1= 40

For the stoichiometry of the reaction one mole of Na2O = 62g produce two mol of NaOH = 2* 40= 80 g

120 g Na2O x 80g NaOH / 62g Na2O=

154.8 g NaOH

A reaction between liquid reactants takes place at - 11.0 degree C in a sealed, evacuated vessel with a measured volume of 45.0
Sati [7]

Explanation:

The given data is as follows.

       T = 11^{o}C = (11 + 273) K = 284 K,     V = 45.0 L

      m = 35 g

As molar mass of chlorine pentafluoride is 130.445 g/mol. Hence, number of moles of chlorine pentafluoride are as follows.

      No. of moles = \frac{mass}{\text{molar mass}}

                             = \frac{35 g}{130.445 g/mol}

                             = 0.268 mol

Now, using the ideal gas equation we will find the pressure as follows.

                          PV = nRT

       P \times 45.0 L = 0.268 mol \times 0.082 L atm/mol K \times  284 K

                       P = 0.139 atm

Thus, we can conclude that pressure of chlorine pentafluoride gas in the given reaction vessel after the reaction is 0.139 atm.
