How many grams of solid KOH are needed to prepare 100.mL of a 1.7 M solution?
moles needed = M x L = ??
mols = grams/molar mass
Solve for grams.
how to prepare 1.7% koh solution
To find the number of grams of solid KOH needed to prepare the solution, you can use the formula:
Number of grams = concentration (mol/L) × volume (L) × molar mass (g/mol)
In this case, the concentration is given as 1.7 M, the volume is given as 100 mL (which is equivalent to 0.1 L), and the molar mass of KOH is 56.11 g/mol.
Let's plug these values into the formula:
Number of grams = 1.7 M × 0.1 L × 56.11 g/mol
Calculating this expression will give you the number of grams of solid KOH needed to prepare the solution.
