Hey, What is the difference between molar mass (g/mol) and atomic mass (=1 unit) ? Under molar mass I wrote this example in school: How heavy is one mole of gypsum (CaSO4)? -> 172.1712 g/mol Under atomic mass I wrote this: 12.011 * 1.6605 * 10^(-24) g = 12.011 ug But I don't understand what…
The task is: Calculate the average atomic mass of the following isotopic mixture: 81.2 of 11/5B%.
Use the table to calculate the average atomic masses. I would be happy to receive answers. Best regards
What is the difference between molecular mass and atomic mass? What is molecular mass?
Hello everyone, I'm writing a chemistry test soon (9th grade). We have to be able to convert the atomic mass unit u into g, which I unfortunately don't understand because I was absent when it was covered in class. I would appreciate it if someone could help me. Thank you in advance!
Hello everyone Today I noticed that the mass number of pure elements is not an integer, but deviates slightly. Can someone explain to me why this is? Theoretically, the mass number should be even, since pure elements only have one isotope. Thanks for your answers!
What is the atomic mass of sulfur S8 in units?:)
