How many grams of KOH are needed to make 250.0 mL of a solution that is to contain 6.70 mgmL of potassium ion?
To find the grams of KOH needed, we first convert the volume to L: 250.0 mL = 0.250 L. Then, calculate the total mass of potassium ion needed: 0.250 L x 6.70 mg/mL = 1.675 mg. Finally, convert mg to grams (1 g = 1000 mg) to find the total grams of KOH required.
