The density of silver metal bar is 10.5 g/cm3 and it occupies a volume space of 0.5l. what is its mass in kilograms (kg).

Density is equal to the ratio of mass to the volume.

The mathematical expression is given as:

Density of silver metal bar=

Convert into g/L

= 0.001 L

Thus, density  =

=

Volume = 0.5 L

Put the values,

=

Now, convert gram into kg

1 g = 0.001 kg

Therefore, mass in kg=  

= 5.25 kg

Thus, mass of silver metal bar in kg=5.25 kg

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
