Question

Find the formula mass for oxalic acid h2c2o4 Use C=12.01, H=1.008 O=16.00

Answer 1

The formula mass of oxalic acid H2C2O4 is =90.036

Explanation

• The formula mass is sum of atomic weights of atoms in a molecule.
• for oxalic acid is the sum of atomic weight of Hydrogen(H) + carbon(C) +oxygen (O).

= (2 x 1.008) + (12.01 x2) + (16 x4)=90.036
