Aluminium Sulfide
According to rules the positive specie is named first and the negative specie is named last.
Molarity is defined as the number of moles dissolved in 1 L of solution .2 mol of NaOH has been dissolved in a volume of 3 L.
we need to then find the number of NaOH moles dissolved in 1 L.
Molarity = number of moles / volume in L
Molarity = 2 mol / 3 L = 0.67 mol/L
Therefore molarity of NaOH - 0.67 M
Using evidence to support explanations is a good practice because it proves that what you are explaining can be verified.
The conversion factor from compound to element is actually
just based on the number of elements in the compound itself.
From the compound C12H22O11, we can say that there are 12
C, 22 H and 11 O, therefore the conversion factors are:
1 mol C12H22O11=12
moles of C
1 mol C12H22O11=22
moles of H
1 mol C12H22O11= 11 moles of O
