The balanced chemical reaction is:
HC2H3O2<span> (aq) +Ba(OH)2 (aq) --> H2O (l) +Ba(C2H3O2)2
</span>
We are given the amount of HC2H3O2 to be used in the reaction. We use this amount as the starting point of our calculations.
0.432 mol HC2H3O2 ( 1 mol Ba(OH)2 / 1 mol HC2H3O2 ) = 0.432 mol Ba(OH)2 needed
Hope this answers the question.
Explanation:
The temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure is known as boiling point.
At the boiling point the liquid and vapor state of a substance remains in equilibrium till the time all molecules of liquid do not turn into vapor.
When all the liquid molecules change into vapor state then only there will occur a rise in temperature.
Properties that do not depend on the amount of matter are known as intensive properties.
For example, boiling point, melting point, density etc.
On the other hand, properties which depend on the amount of matter are called extensive properties.
For example, volume, density etc.
Thus, we can conclude that if you heat a liquid and measure the temperature at which it boils, you are measuring an intensive property.
1 mole of MgS = 24.3 + 32.1 = 56.4 g
35.1 g MgS x 1 mol / 56.4 g = 0.622 mol
M = 0.622 mol / 0.835 L = 0.745 mol/L
To calculate moles from grams using chemical formulas ... However, one mole of magnesium weighs 24.31 g. ... 0.873 g x 95.21 g = 9.17 x 10-3 mol MgCl2.
