A graduated cylinder contains 155mL mL of water. A 17.0g g piece of iron (density = 7.86g/cm 3 g/cm^3 ) and a 23.0g g piece of lead are added. What is the new water level in the cylinder?

Question

A graduated cylinder contains 155mL mL of water. A 17.0g g piece of iron (density = 7.86g/cm 3  g/cm^3 ) and a 23.0g g piece of lead are added. What is the new water level in the cylinder?

DrBob222 · Answer

You MUST have the density of Pb which is about 11.3 g/mL
volume = mass/density
volume Fe = 17.0/7.86 = ? mL
volume Pb = 23.0/11.3 = ? mL
Total volume Pb + Fe = ?
Volume of water level in graduated cylinder is 155 mL + total volume Pb + Fe = ?
