Question

calculate the Mass of 0.5 mole of silver

Answer 1

mass of 0.5 mole of silver =
No . of moles = Given mass / molar mass
mass = no. of moles × molar mass
= 0.5 × 108
= 54g

Answer 2

The mass of 0.5 mole of silver is equal to 54g.

Explanation:

• To calculate the exact mass of the 0.5 moles in silver we have to know the total molar mass in the element of silver.

• The number of the moles is equivalent to the given mass which is then divided by the total molar mass.

• Therefore to find the given mass, we will have to multiply the molar mass with the number of moles of element of silver which are given to us.

• $mass = number of moles \times molar mass$ mass = number of moles x molar mass.

• The molar mass of element silver is equivalent to 108.

• Therefore

          $0.5\times108$ = 54g which is the given mass of silver.
