<p>Work out atom economy for following equation. Sodium sulfate is desired product</p>

Work out atom economy for following equation. Sodium sulfate is desired product

So , sodium sulfate molecular mass is 142.1 g / mol.

Sodium hydroxide has molecular mass of 40 . 0 g / mol. 2 Moles of it so its (40×2)

Molecular mass of na2so4 is 98.1 g / mol

Gives us atom economy of 78.8%
