Step 1: Identify the substance you are working with, which is H2O (water).
Step 2: Find the molar mass of H2O. The molar mass is 18 grams per mole (g/mol).
Step 3: Determine the mass you have, which is 200 grams.
Step 4: Use the formula to calculate the number of moles: Number of moles = mass / molar mass.
Step 5: Plug in the values: Number of moles = 200 grams / 18 g/mol.
Step 6: Calculate the result: 200 divided by 18 equals approximately 11.11 moles.
Molar Mass Calculation – Understanding how to calculate the molar mass of a compound and its application in determining the number of moles from a given mass.
Mole Concept – Applying the mole concept to convert mass to moles using the formula: moles = mass / molar mass.
