The density of a metal is calculated as follows. The weight of 57.4 grams is divided by the volume 6.2 cm3. Using the approximate rule for significant figures in this

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.

A cape is designed for Lady Gaga's covered with 4450 sequins. If a sequin has a volume of 0.0275 cm^3 and the density of 44.3 g/cm^3, calculate the mass in kg of sequins on Lady Gaga's cape.

A sample that has a mass of about 21 g is placed on a balance that has a precision of 0.0001 g. How many significant figures should be reported for this measurement?
