The volume of water displace by crown is 10.7 mL. This will be equal to the volume of crown. Mass of crown is 112 g.
Density of a substance is defined as mass of substance per unit volume. It is mathematically represented as follows:

Putting the values,

The theoretical value of density of silver is
also, 1 mL is equal to
thus, density will be 10.5 g/mL.
This is approximately equal to the calculated value thus, the crown is made up of silver.

Plants are autotrophs, which means that they capable of producing their own "food" from inorganic substances using energy from light or chemical reactions. Plants produce their food mainly by photosynthesis, which utilizes energy in the form of sunlight to convert carbon dioxide in the atmosphere to complex organic molecules as source of food.
