4.using ur rounded density from question 1(c), calculate i) the volume of a lead rod that has a mass of 1986.4g, and ii) the mass of a lead block that has a volume of 112.8cm^3

5. a graduated cylinder contains 3.55ML of water. a piece of non-reactive metal weighing 3865mg is placed in the cylinder, and the water level rises to 4.30ML. is this metal also lead? Explain.

6. the smallest particle of silver that retains the properties of silver is called a(n)

7. the smallest particle of sucrose that retains the properties of sucrose is called

6. An atom.

7. A molecule.

Good luck!

for question 4 and 5 i think you should post previous data too...

anyway just use density = mass / volume

nvm i just saw your other thread
