Question

choose the correct answer. what is the mass of the blue liquid? 100g 40g

Explanation:

Step1: Set up mass - conservation equation

Let the mass of the blue liquid be $x$ grams. The sum of the mass of the blue liquid and the red - liquid equals the mass of the final mixture. So, $x + 60=100$.

Step2: Solve for $x$

Subtract 60 from both sides of the equation: $x=100 - 60$.

Answer:

40g
