Calculate the No. of moles in the following :64 g oxygen molecule (O2)12 g Helium
Question
Solution 1
To calculate the number of moles, we use the formula:
Number of moles = Mass of substance / Molar mass of substance
For Oxygen molecule (O2): The molar mass of O2 = 16 g/mol * 2 = 32 g/mol So, the number of moles = 64 g / 32 g/mol = 2 moles
For Helium: The molar mass of Helium = 4 Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
