Explanation:
Given;
Number of moles of the elements = 3.8moles
Molar mass of Gold = 196.966g/mol
Molar mass of Magnesium = 24.3g/mol
Molar mass of Tin = 118.710g/mol
Molar mass of Bromine = 79.904g/mol
Mass = number of moles x molar mass
Mass of Gold = 3.8 x 196.966 = 748.5g
Mass of Magnesium = 3.8 x 24.3 = 92.3g
Mass of Tin = 3.8 x 118.710 = 451.1g
Mass of Bromine = 3.8 x 79.904 = 303.6g
Answer : 42.3 ml of a 0.266 M 
solution are required.
Solution : Given,
Molarity of solution 1 = 0.266 M
Molarity of solution 2 = 0.075 M
Volume of solution 2 = 150 ml = 0.150 L (1 L = 1000 ml)
Formula used :
where,
= Molarity of solution 1
= Molarity of solution 2
= Volume of solution 1
= Volume of solution 2
Now put all the given values in above formula, we get
(1 L = 1000 ml)
Therefore, 42.3 ml of a 0.266 M solution are required.
