The molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance. View more lessons or practice this subject at www.khanacadem...

Deadass just learnt what my chem teacher has been trying to teach for 2 weeks in under 10 minutes, I had no idea moles and molar mass was this simple, a fact that my chem teacher failed to convey.

*_Summarised by GPT-4_* *(1)* Determine the molar mass of glucose by adding up the molar masses of its constituent elements (Carbon, Hydrogen, and Oxygen) using the periodic table. *(2)* Carbon (C) has a molar mass of 12.01 grams/mole. Hydrogen (H) has a molar mass of 1.008 grams/mole. Oxygen (O) has a molar mass of 16.00 grams/mole. *(3)* The molar mass of glucose = (6 x molar mass of C) + (12 x molar mass of H) + (6 x molar mass of O) = 180.16 grams/mole. *(4)* To find the number of moles in a 1.52 kilogram sample of glucose, convert the kilograms to grams (1.52 kg = 1520 grams). *(5)* Divide the total grams by the molar mass: 1520 grams ÷ 180.16 grams/mole = 8.44 moles of glucose.
