Calculate the number of grams of solute in 500.0 mL of 0.189 M KOH. A)148 B)1.68 C)5.30 × 10³ D)5.30 E)1.68 × 10^-3

Question

Quizplus · Accepted Answer

We can use the formula:

moles of solute = concentration x volume

First, we need to convert the volume from milliliters to liters:

500.0 mL = 0.5000 L

Next, we can plug in the values:

moles of solute = 0.189 mol/L x 0.5000 L 
moles of solute = 0.09450 mol

Finally, we can convert from moles to grams using the molar mass of KOH:

grams of solute = 0.09450 mol x 56.11 g/mol 
grams of solute = 5.30 g

Therefore, the answer is D) 5.30.
