Final answer:
To find the mass of the marble, the volume of the marble is needed, which can be found by the water displacement method. Since the water level increase wasn't provided, the marble's mass cannot be calculated.
Step-by-step explanation:
To determine the mass of the marble, one needs to utilize the definition of density. Density is defined as mass per unit volume (ρ = m/v). In this case, we know the density (0.5 g/cm3) and the volume. The volume of the marble can be found by displacement method. When the marble is added to the graduated cylinder, the water level rises, which gives you the volume of the marble. However, this information was not provided in the question. We actually cannot determine the mass of the marble without knowing how much the water level rose in the graduated cylinder after the marble was added as this increase would directly correlate to the marble's volume. With this piece of vital information missing, the mass cannot be accurately determined.
