we dissolve 18.9 g of li, o (molar mass = 29.9 g/mol) ini sufficient water to make 650 ml of
solution
question
what is the molarity of the solution?

The solution has a molarity of 0.97 M

Explanation:

Step 1: Given data

Mass of LiO = 18.9 grams

Molar mass of LiO = 29.9 g/mol

Volume = 650 mL = 0.650 L

Step 2: Calculate number of moles

Number of moles of LiO = Mass of LiO / Molar mass of LiO

Moles LiO = 18.9 grams / 29.9 grams/mol

Moles LiO = 0.6321 moles

Step 3: Calculate molarity

Molarity = Number of moles per volume

Molarity = Moles per liter

Molarity LiO = Moles LiO / volume solution

Molarity LiO = 0.6321 mol / 0.65 L

Molarity LiO = 0.97 M

The solution has a molarity of 0.97 M

the maximum mass of nh3 is nh3 in grams

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
