A gallon of milk weighs 8.09 lb. Calculate the density of milk in grams per cubic centimeter.

I have a chemistry question, it asks: "In the lab, you measure the density of a metal to be 4.16 g/cm3. The handbook value for the density of this metal is 4.018 g/mL. What is the percent error? Pay close attention to the significant figures in your answer, as you should in the lab." My question is: What do we do? Are we trying to find the volume and mass from the given density of 4.018? How do we do that?

1) The weight of a rock is measured to be 0.075 lbs. After placing the rock in a graduated cylinder containing 17.09 mL of water, the new measurement is 28.76 mL. Calculate the density of the rock in g/mL. 2) A person measures the velocity of a biker riding in a straight line along a sidewalk using a stopwatch. The time it took for the biker to pass 29 squares on the sidewalk was 11.29 seconds. The area of the squares on the sidewalk was measured to be 2731 in2. Calculate the velocity of the biker in m/s.Note: 1 in = 2.54 cm 3) A hollow square metal tube has a measurement of 1.98 in for each side and a weight of 60.92 g. The volume of empty space inside the tube was measured to be 2.44 in3. If the density of the metal used in constructing the tube is 11.46 g/mL, calculate the length of the tube in inches.Note: 1 in = 2.54 cm, 1 cm3 = 1 mL 4) Porosity is a measure of the void or empty spaces in a material and is a fraction of the volume of voids over the total volume. The density of the…

A. Type the number 1340000 in scientific notation. B. Type the number 0.000354 in scientific notation. C. Type the number 3.14×103 in standard notation.

One carat is equivalent to a mass of 0.200 g. Use the fact that 1 kg (1000 g) has a weight of 2.205 lb under certain conditions, and determine the weight of a 1414 carat diamond in pounds (lb).

Iron has a density of 7.86 g/cm37.86 g/cm3 (1 cm3=1 mL1 cm3=1 mL). Calculate the volume (in dLdL) of a piece of iron having a mass of 4.32 kgkg . Note that the density is provided in different units of volume and mass than the desired units of volume (dLdL) and the given units of mass (kgkg). You will need to express the density in kg/dLkg/dL (1 cm3 = 1 mL1 cm3 = 1 mL) before calculating the volume for the piece of iron. Express your answer to three significant figures.

An astronaut on the moon places a package on a scale and finds its weight to be 19 N. (a) What would the weight of the package be on the earth? N(b) What is the mass of the package on the moon? kg(c) What is the package's mass on earth?
