Question

michael is conducting an experiment where he mixes substance a (5g) with substance b to produce substance c (9g). based on the conservation of mass, how many grams should substance b have?

Explanation:

Step1: Apply the law of conservation of mass

According to the law of conservation of mass, the mass of reactants equals the mass of products. Let the mass of substance B be \(x\). Then \(5 + x=9\).

Step2: Solve the equation for \(x\)

Subtract 5 from both sides of the equation: \(x = 9 - 5\).

Answer:

\(4\) grams.
