WebUsing the formula of molarity, we can calculate the number of moles in oxalic acid (H 2 C 2 O 4.2H 2 O) As we know, the molar mass of oxalic acid (H 2 C 2 O 4.2H 2 O) = 126 g/mol. Using, m=3.15g Thus, the mass of oxalic acid (H 2 C 2 O 4.2H 2 O) needed to prepare 250 ml,1 M aqueous solution of oxalic acid is 3.15 grams.
Web1 L solution of N a 2 C O 3 and N a O H was made in H 2 O. 1 0 0 mL of this solution required 2 0 mL of 0. 4 M H C l in the presence of phenolphthalein. However, another 1 0 0 mL sample of the same solution required 2 5 mL of the same acid in the presence of methyl orange as an indicator. WebExamples of molecular weight computations: C[14]O[16]2, S[34]O[16]2. Definitions of molecular mass, molecular weight, molar mass and molar weight. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
