Answer:
Density = 1027.3 [kg/m3]
Step-by-step explanation:
To solve this problem we must use the concept of density which is defined as the relationship between mass and volume, which can be determined by the following equation.
density = m/v
m = mass = 308.19 [gramm] = 0.30819 [kg]
v = volume = 300 [mL] = 0.3 [Lt] = 0.0003 [m3]
density = (0.30819/0.0003)
density = 1027.3 [kg/m3]
