"An object weighing 10.01 grams is placed in a graduated cylinder containing 3.90 mL of water. If the total volume of the object and water is 9.06 mL, then what is the density of the object in g/mL?"
1 answer:
Answer:
Density of the object = 1.9399g/mL
Explanation:
Mass of object = 10.01g
Volume of water = 3.90mL
Volume of Object + Water = 9.06mL
Therefore, volume of Object = Volume of Object + Water - Volume of Water
= 9.06mL - 3.90mL
= 5.16mL
Density by definition is the mass per unit volume of a substance.
Density of the object = mass/volume
= 10.01/5.16
= 1.9399g/mL or 1.94kg/m3
