What mass of NaOH is needed to make 5 L of a 0.1 mol/L solution? (Relative atomic masses: Na = 23, O = 16, H = 1.)
Answer and explanation
Correct answer: D. g
- Step 1: mol.
- Step 2: g.
Answer
g.
Why not the others: g: The volume was left out. g: The concentration was left out. g: The moles were given instead of the mass.
