Theyâll join 20,000 of their colleagues who crisscross the globe on more than 3,500 flights a day, providing safe and comfortable service to Deltaâs 175 million annual customers. âI am thrilled to be a part of the Delta team,â said Tyler V., one of the airlineâs newest flight attendants.
The mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbonâs molar mass is 12.011 g/mol, and magnesiumâs molar mass is 24.3050 g/mol.
The mass per mole of a substance is called its molar mass. Since the atomic mass unit (amu) is defined as 1/12 of the mass of the 12C atom, it follows that the molar mass of a substance, measured in grams per mole, is numerically equal to its mean atomic or molecular mass measured in amu.
