Genetics 101

1. You want to make a 100ml solution of 0.1N MgCl₂. You are provided with a 1N stock solution of MgCl₂. The volume of H₂0 and the stock MgCl₂ that’ll needed to be mixed is

• 90ml H₂0 + 10ml MgCl₂

• 99ml H₂0 + 1ml MgCl₂

• 80ml H₂0 + 20ml MgCl₂

• 9ml H₂0 + 91ml MgCl₂

1. To make a 1000ml solution of 1N MgCl₂: you add 100ml of 10N MgCl₂ stock solution and 900ml of H₂0. What is the dilution factor?
