Given that a mass of a ball is (36.0 g), and the volume is (8.0 mL), what is the ball's density in g/mL?

4.5g/mL

Explanation:

Given parameters:

Mass of ball  = 36g

Volume of the ball  = 8mL

Unknown:

Density of the ball  = ?

Solution:

Density is the mass per unit volume of a substance.

          Density  =  

So;

 Density  =    = 4.5g/mL

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

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.
