360g of water is equivalent to 12.04 x 10^24 molecules. To calculate, use water's molar mass (18g/mol) and Avogadro's number (6.02 x 10^23 molecules/mol). Divide 360g by 18g/mol to get 20 moles, then multiply by 6.02 x 10^23 to find the number of molecules.
FAQs & Answers
- What is Avogadro's number? Avogadro's number is 6.02 x 10^23, which represents the number of molecules in one mole of a substance.
- What is the molar mass of water? The molar mass of water (H2O) is 18 g/mol, calculated from the weights of hydrogen and oxygen.
- How do you calculate the number of molecules from grams? To calculate the number of molecules from grams, divide the mass by the molar mass to get moles, then multiply by Avogadro's number.
- Why is understanding water molecules important? Understanding water molecules helps grasp essential concepts in chemistry, biology, and environmental science.
