Express your answer to two significant figures and include the appropriate mo ( Value Units My Answers Cu Wood

Explanation / Answer

mass of the wooden block = .8 kg

density of wood = 0.6 x 10^3 kg/m^3

mass / volume = density

volume = mass / density = .8/ 0.6 x 10^3

volume = 1.33 x 10^-3 m^3

so weight of liquid displaced = volume x density of liquid = 1.33 x 10^-3 m^3 x 1000 = 1.33 kg

total weight = weight of copper + weight of the wood

= Wcu + .8kg

1.33 - .8 = weight of copper = 0.53kg
