Question

what is the mass of the red liquid? 100g 60g

Explanation:

Step1: Set up the equation

Let the mass of the red liquid be \(x\) grams. According to the mass conservation principle (the sum of the masses of the two components equals the mass of the final mixture), we have the equation \(40 + x=100\).

Step2: Solve the equation for \(x\)

Subtract \(40\) from both sides of the equation: \(x = 100 - 40\).

Answer:

\(60g\)
