An experiment with a pycnometer resulted in the following data:
Mass of Pycnomter = 25.428 g
Mass of Pycnometer filled with water = 44.021 grams
Mass of Pycnometer filled with liquid X = 41.421 grams
a) What is the specific gravity of liquid X?
b) If methanol (Specific Gravity = 0.790) was used rather than water in measuring the density of irregular objects, how would that affect the result? Why?

Solve these problems about lumber dimensions.
(a) To describe to a European how houses are constructed in the US, the dimensions of “two-by-four” lumber must be converted into metric units. The thickness ×× width ×× length dimensions are 1.50 in. ×× 3.50 in. ×× 8.00 ft in the US. What are the dimensions in cm ×× cm ×× m?
(b) This lumber can be used as vertical studs, which are typically placed 16.0 in. apart. What is that distance in centimeters?
5. The volume of an irregularly shaped solid can be determined by immersing the solid in a liquid and measuring the volume of liquid displaced. Find the volume and density of the following:
a. An irregular piece of the mineral quartz is found to weigh 12.4 g. It is then placed into a graduated cylinder that contains some water. The quartz does not float. The water in the cylinder was at a level of 25.2 mL before the quartz was added and at 29.9 mL afterward.
b. The volume of a sample of lead shot is determined using a graduated cylinder, as in part (a). The cylinder readings are 16.3 mL before the shot is added and 21.7 mL after. The sample of the shot weighs 61.0 g.
c. A sample of coarse rock salt is found to have a mass of 11.7 g. The volume of the sample is determined by the graduated cylinder method described in (part a), but kerosene is substituted for water because the salt will not dissolve in kerosene. The cylinder readings are 20.7 mL before adding the salt and 26.1 mL after.

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 solid material used to create 6 pieces of 0.99 cm diameter and 1.17 cm height cylindrical beads is determined to be 1.84 g/mL. These beads were then placed in a flask and were filled to the 43 mL mark with a salt solution. The total weight measured of the beads and the salt solution was 47.22 g. Upon further inspection, it was found that manufacturing defects caused the measured porosity of the beads to be at 20%. Assuming that the solution was able to fully fill the empty spaces inside the beads, calculate the density of the salt solution. 3. A chocolate…arrow_forward
