Total number of atoms = 7
Total number of H atom = 5
% of H in ammonium hydroxide = 5/7 ×100 = 71.4 %
There are 5 steps:
1- measure the mass of the container
2- measure the volume of the liquid
3- measure the combined mass of the liquid and the container.
4-determine the mass of the liquid alone
5-divide the mass by the volume.
They are alike bc they both have 13 protons and neutrons
In order to find your answer you need to be <span>measuring entropy, so you will be using the following formula:
</span><span>delta S= S of (N2H4) + S of ( H2) - [2( S of NH3)]
</span>Hope this is very useful for you
dissolves in water to give
and
ions according to the following reaction:
-------->
+ 2
So, according to the above reaction, 1 mole of
produce 2 moles of
ion,
So, 0.3 mole will give = 0.3 x 2 = 0.6 moles of
ion
So, Molar concentration =
Note: 1L = 1000mL
