An empty container has a mass of 50g. When a 75 mL of oil is placed in container, the the total mass is 120 g. Calculate the density of just the oil.
Question
An empty container has a mass of 50g. When 75 mL of oil is placed in the container, the total mass is 120 g.
Calculate the density of just the oil.
Solution
Sure, here are the steps to calculate the density of the oil:
Step 1: Find the mass of the oil. You can do this by subtracting the mass of the empty container from the total mass. So, 120g (total mass) - 50g (mass of container) = 70g (mass of oil).
Step 2: Convert the volume of the oil from mL to cm^3, since the density is typically measured in g/cm^3. In this case, 1 mL is equivalent to 1 cm^3, so the volume of the oil is 75 cm^3.
Step 3: Use the formula for density, which is mass/volume. So, the density of the oil is 70g/75cm^3 = 0.93 g/cm^3.
