At room temperature, the element bromine is a liquid with a density of 3.12 g/mL. a Calculate the mass of 542 mL of bromine.
Mass = blank g
b What volume does 60.0 g of bromine occupy?
Volume =
mL

The answer to both solution is as follows:-

All the data is given in the question,

The formula we will use is as follows:-

 = 1691.04 g

Hence, the mass of the bromine is 1691.04g

The volume of bromine =

The volume of bromine is 19.23mL.

Hence, the mass and the volume are 1691.4g and 19.23ml.

A. 1691.04 g

B. 19.23 mL

Explanation:

The following data were obtained from the question:

Density of bromine = 3.12 g/mL.

A. Determination of the mass of bromine.

Density of bromine = 3.12 g/mL.

Volume of bromine = 542 mL

Mass of bromine =?

Density = mass /volume

3.12 = mass /542

Cross multiply

Mass of bromine = 3.12 × 542

Mass of bromine = 1691.04 g

B. Determination of of volume of bromine.

Density of bromine = 3.12 g/mL.

Mass of bromine = 60 g

Volume of bromine =...?

Density = mass /volume

3.12 = 60 / volume

Cross multiply

3.12 × volume = 60

Divide both side by 3.12

Volume of bromine = 60/3.12

Volume of bromine = 19.23 mL.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
