Final answer:
To solve the formula d = mV for the variable m, we need to isolate m on one side of the equation by dividing both sides by V.
Step-by-step explanation:
To solve the formula d = mV for the variable m, we need to isolate m on one side of the equation. To do this, divide both sides of the equation by V, which gives us m = d/V.
For example, if the density d is 2 g/cm³ and the volume V is 4 cm³, then the value of m would be 0.5 g.
