molar mass of KHP ( C8H5O4K)= 8*12+5+4*16+39=204
( atomic weights : C=12, H=1, K=39 and O= 16)
moles of KHP= mass/molar mass = 1.513/204 =0.0074
The reaction between KHP and NaOH is
KHC8H4O4(aq) + NaOH(aq) => KNaC8H4O4(aq) + H2O(l)
1 mole of KHP requires 1 mole of NaOH;
moles of KHP=0.0074
moles of NaOH= 0.0074
concentration of NaOH= moles/ Volume in L, 1000ml= 1L, 14.8ml= 14.8/1000L=0.0148L
concentration of NaOH=0.0074/0.0148=0.5M
The molarity of NaOH is 0.5M
Molar Mass:
In chemistry, the molar mass of a compound is defined as the mass of a sample of that compound divided by the amount of substance. This is the number of moles of that sample measured in moles.
Molarity:
Molarity is used to describe the concentration of a solution. Molarity, also called molarity, is the number of moles of solute (dissolved substance) per liter of solution.
