An liquid's mass is 79.6 g. A student measures the volume to be 42.5mL. What is the density of the liquid?

The answer is

Explanation:

The density of a substance can be found by using the formula

From the question

mass of liquid = 79.6 g

volume = 42.5 mL

The density of the liquid is

We have the final answer as

1.87 g/mL

Hope this helps you

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.
