Question

Explain the similarities and differences between a 1M solution of NaOH and a 1m solution of NaOH

Answer 1

Answer:

Similarity - 1 mol of NaOH in 1M and 1m.

Difference - 1M - 1 mol NaOH in 1L solution,

1m - 1 mol NaOH in 1000g solvent (water).

Explanation:

M - Molarity,  the number moles of solute are dissolved in 1 L of solution.

m - Molality is the number of moles of solute per 1 (kg) kilogram = 1000 g of solvent.

Similarity - 1 mol of NaOH in 1M and 1m.

Difference - 1M - 1 mol NaOH in 1L solution,

1m - 1 mol NaOH in 1000g solvent (water).
