To determine the volume that can be prepared from a given mass of a substance, you need to calculate the amount of substance (in moles) and then use the molarity to find the volume.
The molar mass of NaOH (sodium hydroxide) is 22.99 g/mol for Na, 16.00 g/mol for O, and 1.01 g/mol for H.
Let's calculate the amount of NaOH in moles:
Amount of NaOH = mass of NaOH / molar mass of NaOH = 2.54 g / (22.99 g/mol + 16.00 g/mol + 1.01 g/mol) = 2.54 g / 40.00 g/mol = 0.0635 mol
Now, we can use the molarity (1.0 M) to find the volume of the solution:
Volume of solution = Amount of NaOH / Molarity = 0.0635 mol / 1.0 mol/L = 0.0635 L or 63.5 mL
Therefore, from 2.54 g of NaOH, you can prepare 63.5 mL of a 1.0 M NaOH solution.
