Q: Which equation best represents the relationship between the volume of extracellular matrix ($$V_{ECM}) $$and the total volume ($$V_{total}) in $$connective tissue, if the matrix makes up 80% of the tissue?

$$V_{ECM} = 0.8 \times V_{total}$$

Q: Which formula would you use to calculate the percentage of connective tissue in a sample, given the mass of connective tissue ($$m_{CT}) $$and the total mass ($$m_{total}$$)?

$$\text{Percentage} = \frac{m_{CT}}{m_{total}} \times 100$$
