Question

what is the mass of the blue liquid? 100g 40g

Explanation:

Step1: Set up the equation

Let the mass of the blue liquid be \(x\) grams. According to the mass conservation principle (the sum of the masses of the two liquids before mixing is equal to the mass of the mixture), we have the equation \(x + 60=100\).

Step2: Solve the equation for \(x\)

Subtract 60 from both sides of the equation \(x+60 - 60=100 - 60\).

Answer:

\(40g\)
