Answer: The concentration of vanilla extract in the solution is 0.50 % (m/m)
Explanation:
We are given:
Mass of vanilla extract (solute) = 4 grams
Mass of cake's batter (solvent) = 800 grams
Mass of solution = Mass of solute + Mass of solvent = 4 + 800 = 804 grams
To calculate the mass percentage (concentration) of vanilla extract in the solution, we use the equation:
[tex]\text{Concentration of vanilla extract}=\frac{\text{Mass of vanilla extract}}{\text{Mass of solution}}\times 100[/tex]
Putting values in above equation, we get:
[tex]\text{Concentration of vanilla extract}=\frac{4g}{804g}\times 100\\\\\text{Concentration of vanilla extract}=0.50\%[/tex]
Hence, the concentration of vanilla extract in the solution is 0.50 % (m/m)
