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.
Answer:
Theoretical yield is 20%.
Explanation:
Percent yield = [(actual yield)/(theoretical yield)] %
Theoretical yield is calculated amount of product by using stoichiometric ratio between reactant and product.
Actual yield is the amount of product which is experimentally obtained.
Here theoretical yield is 20.0 g and actual yield is 4.0 g.
So, percent yield = % = 20%
