A student was given an unknown metal.  The student determined that the mass of the metal was 30.2 g.  The student placed the metal in a graduated cylinder filled with 20.0 mL of water.  The metal increased the volume of water to 22.9 mL.  Calculate the density of the metal and determine the identity of the metal using the table below.

The mass of an empty 10ml graduated cylinder is 8.6g. What is the mass of a graduated cylinder with 10ml of water in it? Use this mass and the mass of the empty graduated cylinder to calculate the mass of the 10ml of water?

Suppose you are trying to find the volume of a box based on the given measurements for the length, width, and height of the box, where the height was measured in two parts.      length, l = 2.20 in      width, w = 3.71 in      height, h = 10.4 in + 1 in Calculate the height, ℎ, of the box, first keeping all digits, then rounding to the proper number of significant figures. unrounded h = ____in rounded h =____  in  Calculate the volume (V) of the box using V =l x w x h. Round to the proper number of significant figures.  v=_____in3

A Chemistry student had a cold and took 2.3 teaspoons (tsp) of cough syrup. If the syrup had a density of 0.950 g/mL and there is 6.0 mL in 1 tsp, what was the mass, in grams, of the cough syrup? Provide numerical values in standard notation (not scientific notation) not including units.

A chemist weighed out 7.2g of mercury. Calculate the number of moles of mercury she weighed out. Be sure your answer has the correct number of significant digits.

A chemistry student needs 35.0 mL of dimethyl sulfoxide for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of dimethyl sulfoxide is 1.10 g·cm -3 Calculate the mass of dimethyl sulfoxide the student should weigh out. Be sure your answer has the correct number of significant digits. ?
