Calculate the mass of 20.0 moles of sc

900g

Explanation:

Given parameters:

Number of moles  of Sc  = 20moles

Unknown:

Mass of Sc  = ?

Solution:

To find the mass of the scandium given, we use the expression below:

      Mass  = Number of moles x molar mass

Molar mass of Sc   = 45g/mol

So;

     Mass of Sc  = 20 x 45 = 900g
