Answer 1

B.




Explanation: Molar mass: the mass in grams of one mole of any substance (elements or compounds). Also known as atomic mass, atomic weight, molecular weight (MW), and formula weight (FW), but these terms can be misleading. 1 mole 12C = 6.022 x 1023 atoms 12C = 12 g 12C. 12C is defined to be exactly 12 g.
