Whether the combination of cork and lead will sink or float is to be determined. Concept introduction: Volume is an important physical quantity in chemistry that is measured by the SI unit called cubic meter ( m 3 ) It is defined as the quantity of space occupied by a cube with edge length of 1 m . An important unit used for expressing volume is liter ( L ) . 1 liter refers to the volume of a cube with edge length of 1 dm that is 1 L = 1 dm 3 . The density of any object is obtained when the mass of object in grams is divided by volume of an object in milliliters. So it is denoted by unit: gram per milliliter. Density is directly associated to the mass of an object. The higher the mass of the substance higher will be its density. Density is inversely associated to the volume of a substance. The lower the volume of the substance higher will be its density. Density is associated to how the particles are packed in a substance, which in turn determines its state. The state of a substance defines the density.

Volume is an important physical quantity in chemistry that is measured by the SI unit called cubic meter (m3)
It is defined as the quantity of space occupied by a cube with edge length of 1m. An important unit used for expressing volume is liter (L). 1 liter refers to the volume of a cube with edge length of 1dm that is 1L=1dm3.
The density of any object is obtained when the mass of object in grams is divided by volume of an object in milliliters. So it is denoted by unit: gram per milliliter.
Density is directly associated to the mass of an object. The higher the mass of the substance higher will be its density. Density is inversely associated to the volume of a substance. The lower the volume of the substance higher will be its density.
Density is associated to how the particles are packed in a substance, which in turn determines its state. The state of a substance defines the density.
A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 11.10 g.L-¹. The geochemist also measures the
concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 4.30 g⋅L¯¹.
Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate
the percentage of Lake Parsons which has evaporated since it became isolated.
Be sure your answer has the correct number of significant digits.
A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 69.32 g.L The geochemist also measures the
concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 5.02 g⋅L¯¹.
Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate
the percentage of Lake Parsons which has evaporated since it became isolated.
Be sure your answer has the correct number of significant digits.
A chemistry student needs
70.0mL
of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of pentane is
·0.626gcm−3
. Calculate the mass of pentane the student should weigh out.
