Answer:
3.34 M or 3.34 mol/L
Step-by-step explanation:
The formula for molarity is moles of solution ÷ liters of solution. So, we have to convert grams into moles and mL to L.
To convert grams to moles, first find the molar mass of CH₃COOH by looking at the atomic mass of each individual element.
C - 2(12.01) = 24.02
H - 4(1.01) = 4.04
O - 2(16.00) = 32.00
= 60.06
Now divide the number of grams by the molar mass.
10.0 g CH₃COOH ÷ 60.06 g = 0.167 mol CH₃COOH
To convert milliliters to liters, divide by 1000.
50.0 mL ÷ 1000 = 0.05 L
Now we can calculate the molarity.
M = moles of solution ÷ liters of solution
= 0.167 mol ÷ 0.05 L
= 3.34 M or 3.34 mol/L
The molarity is 3.34 M.
Hope that helps.
