Answer: The number of molecules of water in given amount of oxalic acid is
Explanation:
To calculate the number of moles, we use the equation:
Given mass of oxalic acid = 630 mg = (Conversion factor: 1 g = 1000 mg)
Molar mass of oxalic acid = 126 g/mol
Putting values in above equation, we get:
Chemical formula fr oxalic acid is
By Stoichiometry:
1 mole of oxalic acid contains number of water molecules.
Thus, 0.005 moles of oxalic acid will contain number of water molecules.
Hence, the number of molecules of water in given amount of oxalic acid is
