Tutorial Exercise A solid piece of lead has a mass of 26.69 g and a volume of 2.38 cm³. From these data, calculate the density of lead in SI units (kilograms per cubic meter). Step 1 The density of lead is 1.13 x 104 kg/m³, so we should expect our calculated value to be close to this value. The density of water is 1.00 × 103 kg/m³, so we see that lead is about 11 times denser than water, which agrees with our experience that lead sinks. Step 2 Density is defined as p = m/V. We must convert to SI units in the calculation. %3D Step 3 3 cm 1 kg 1000 g cm3 1 m 1 kg 1000 g cm cm3 1 m3 x 104 kg/m3 II II

An object has a density of 4.4 g/cm3. If the object has a mass of 11.4 g and is placed in a graduated cylinder of water that begins at 50. mL, what will the volume of the water within the graduated cylinder measure after the object is placed inside the water in mL? Calculate your answer to the nearest tenth of a mL using the correct units in your answer. (Note: Pay attention to exactly what is being asked here. You want the final volume of the water, not the object itself). Round your answer to 1 decimal place.

Write your detailed solution starting with the identification of the given quantities. You purchase a rectangular piece of metal that has dimensions 5 x 15 x 30 mm and mass 0.0158 kg. The seller tells you that the metal is gold. To check this, you compute the average density of the piece. What value do you get? Were you cheated
PLEASE SEND THE ANSWER IN 5 MINUTES !!! Suppose that you plot the mass (y-axis, in g) versus volume (x-axis, in cm3) of 4 different geometrical objects on a graph paper. When you plot, you see that 3 of the objects seem to line up. Then, for the best fit line to these 3 objects, assume that you get the following slope points: Slope point 1 : (1;1.1) Slope point 2 : (11;28.5) Using these slope points, calculate the density of these 3 objects in units of g/cm .Give Your answer with 3 significant figures.
