The formula to calculate the missing volume is:
\[ \text{V_T} = \text{V_A} + \text{V_B} \]
Where:
Additive volume refers to the concept where the total volume of a mixture is the sum of the volumes of its individual components. This principle is commonly used in chemistry and physics to determine the volume of a mixture when the volumes of the individual substances are known. It assumes that the volumes are additive and that there is no significant volume change upon mixing.
Let's assume the following values:
Using the formula:
\[ \text{V_T} = 40 + 30 = 70 \text{ units} \]
The missing volume is 30 units.
