Module 6.2 Solutions & Molarity Flashcards
1
Q
When a compound dissolves in another material it forms a homogeneous mixture called a ?
A
Solution
2
Q
Solutes
A
component in a solution that is in smaller amount
ex. salt water solution, less salt so it is the solute
3
Q
Solvent
A
component in a solution that is in larger amount
ex. salt water solution, more water so it is the solvent
4
Q
Molarity formula = ?
A
M=
grams (solute) / molecular weight (solute)
———————————————————
ml (solution) / 1000

Q
Molarity
25 grams of NaCl (MW=58.5) dissolved to make 550 ml solution
A
M= 25g / 58.5mw = 0.427.. / (550/1000) = 0.777
