Calculate the morality of 5% of naoh solnrnshortly solve
Accepted Answer
To calculate the molarity of a 5% NaOH solution, we need to know the density of the solution. Assuming the density is approximately 1.05 g/mL, we can follow these steps:
1. Convert the percentage to grams: 5% NaOH means 5 g NaOH per 100 g solution.
2. Calculate the mass of the solvent: 100 g solution - 5 g NaOH = 95 g H2O
3. Convert the mass of water to volume: 95 g H2O / 1 g/mL = 95 mL H2O
4. Calculate the moles of NaOH: 5 g NaOH / 40 g/mol = 0.125 mol NaOH
5. Calculate the molarity: 0.125 mol NaOH / 0.095 L = 1.32 M
Therefore, the molarity of a 5% NaOH solution (assuming a density of 1.05 g/mL) is approximately 1.32 M.
