It looks like you are asking for the weights or molar masses of various chemical compounds. Let's break down each component:

  1. W(OвH2O2) - This appears to represent hydrogen peroxide (H2O2). The molar mass of H2O2 is approximately 34.01 g/mol.

  2. W(OвH3PO4) - This represents phosphoric acid (H3PO4). The molar mass of H3PO4 is approximately 98.00 g/mol.

  3. W(OвCH3COONa) - This represents sodium acetate (CH3COONa). The molar mass of CH3COONa is approximately 82.03 g/mol.

  4. W(OвC3H7OH) - This represents isopropyl alcohol (C3H7OH or isopropanol). The molar mass of isopropyl alcohol is approximately 60.10 g/mol.

If you are looking for something specific beyond just the molar masses or if you meant something different with "W", please provide additional context, and I would be happy to assist you further!
