A chemist adds 175.0 mL of a 28.8 g/dL calcium bromide (CaBr2) solution to a flask. Calculate the mass in grams of calcium bromide the chemist has added to the flask. Round your answer to 3 significant digits

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.

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
