We're being asked to determine the mass percent of a 2 m H3PO4
For this problem follow the steps:
Step 1. Establish the composition of 2 m H3PO4 and formula of mass percent
Step 2. Determine the mass of H3PO4
Step 3. Determine the mass of solvent
Step 4. Calculate mass percent
Which of the following represents the mass percent of H3PO4 (MM = 98) in a 2.00 m aqueous H3PO4 solution?
