A reagent bottle contains 5.00g of NaOH.how many milliliters of a 2.00M silution can be prepared from this weight of NaOH?
To determine the volume of a 2.00M solution that can be prepared from 5.00g of NaOH, we need to use the equation:
Molarity (M) = moles (mol) / Volume (L)
First, we need to calculate the number of moles of NaOH using its molar mass:
Molar mass of NaOH = 22.99 g/mol (for Na) + 16.00 g/mol (for O) + 1.01 g/mol (for H)
= 39.99 g/mol
Moles of NaOH = Mass (g) / Molar mass (g/mol)
= 5.00 g / 39.99 g/mol
= 0.125 mol
Now, we can rearrange the equation to find the volume of the solution:
Volume (L) = moles (mol) / Molarity (M)
= 0.125 mol / 2.00 mol/L
= 0.0625 L
Finally, we can convert the volume to milliliters:
Volume (mL) = Volume (L) * 1000
= 0.0625 L * 1000
= 62.50 mL
Therefore, 62.50 mL of a 2.00M solution can be prepared from 5.00g of NaOH.
