Answer:
A. 1.11[mL/g]
Explanation:
We have to remember the expression to calculate the density, which says it's the relationship between mass and volume.
We can calculate the different densities for each of the samples.
density1 = m/V = 200/180 = 1.11[mL/g]
density2 = m/V = 300/270 = 1.11[mL/g]
density3 = m/V = 400/270 = 1.11[mL/g]
According to the initial data, we can determine that the density corresponds to 1.11 [mL/g]
