7 0

Answer:

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

What volume of water is needed for 0.196 mol of CdCl2 to prepare a 3.91 M solution? L
Brilliant_brown [7]

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Explanation:

Data given:

moles of CdCl_{2} = 0.196 Moles

Molarity of the solution = 3.91 M

Volume in litres =?

molarity is calculated by the formula:

molarity = \frac{number of moles}{volume in litres}

putting the values in the above formula and rearranging it for volume:

volume = \frac{number of moles}{molarity}

volume = \frac{0.196}{3.91}

volume = 0.050 litres

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Molarity is the number of moles present in a given volume of solution which is given in litres. It is the measurement of the concentration of particular solute in a solution.
