Consider a beaker of water sitting on the pan of an electronic scale that has been tared. A metal weight hanging from a string is suspended in the water and the mass reading on the scale reads 0.10 g. The metal weight falls from the string, rests on the bottom of the beaker, and the reading becomes 0.54 g. (Density water-0.9982 g/ml) What is the mass of water displaced by the metal weight? incorreci, o/1 What is the volume of water displaced by the metal weight? ml not answered 0/1 What is the volume of the metal weight? ml not answered 0/1 What is the mass of the metal weight? not answered 0/1 What is the density of the metal weight? g/ml not answered 0/1

The melting point of sodium chloride, table salt, is 801 C. What is this temperature in degrees Fahrenheit and in kelvins?

The mass unit associated with density is usually grams. If the volume (in mLmL or cm3cm3) is multiplied by the density (g/mLg/mL or g/cm3g/cm3) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 3.00 in3in3 and density of 0.242 g/cm3g/cm3, how much would it weigh in grams? 1 in3=16.39 cm31 in3=16.39 cm3.

You are to give ampicillin, with a recommended dose of 35 mg/kgmg/kg , to a child with a mass of 21 kgkg . If stock on hand is 250 mg/capsulemg/capsule, how many capsules should be given?   Express the number of capsules as an integer.

If 10.00 mL (measured using a volumetric pipette) of a solution is pipetted into a 50 mL beaker which weighs 43.015 g an the combined mass of the beaker and liguid is 57.762 g, what is the density of the liquid? Your answer should have 4 sig. figs

Theodore plans on a taking 75 concrete pavers from his neighbor's yard. The pavers are made of medium concrete that has a density of 1.65 g/mL. If each paver is 1.0 ft ×12.0 in ×7.5 cm, what is the total mass, in tons, of pavers?

Suppose that an in-ground swimming pool has a length and width of 22.0 ft and 39.5 ft, respectively, and a depth of 4.5 ft. What volume of water, in liters (L), is needed to fill this pool?

The radius of a copper (Cu) atom is roughly 1.3x10−10 m. How many times can you divide evenly a 223.3−cm long piece of copper wire until it is reduced to two separate copper atoms? (Assume there are appropriate tools for this procedure and that copper atoms are lined up in a straight line, in contact with each other. Round off your answer to an integer.)

The mass of a beaker is 5.333 g. After 5.00 mL of a concentrated hydrochloric acid solution is pipetted into the beaker, the combined mass of the beaker and the hydrochloric acid sample is 11.229 g. From the data, what is the measured density of the hydrochloric acid solution?

You are assigned the task of separating a desired granular materialwith a density of 3.62 g/cm3 from an undesired granularmaterial that has a density of 2.04 g/cm3. You want to dothis by shaking the mixture in a liquid in which the heaviermaterial will fall to the bottom and the lighter material willfloat. A solid will float on any liquid that is more dense. Usingan Internet-based source or a handbook of chemistry, findthe densities of the following substances: carbon tetrachloride,hexane, benzene, and diiodomethane. Which of theseliquids will serve your purpose, assuming no chemical interactiontakes place between the liquid and the solids?
