What is the molar mass of cryolite (Na₃AlF₆)? A)209.9 g/mol B)185.3 g/mol C)210.0 g/mol D)104.2 g/mol E)68.97 g/mol

Question

Quizplus · Accepted Answer

To find the molar mass of cryolite, we need to add up the atomic masses of all the elements in its formula. 
Na: 1 x 22.99 = 22.99 
S: 1 x 32.06 = 32.06 
B: 13 x 10.81 = 140.53 
Al: 1 x 26.98 = 26.98 
F: 16 x 18.99 = 303.84

Total = 526.4 g/mol

Therefore, the correct answer is C) 210.0 g/mol, which is the closest answer to 526.4 g/mol when rounded to one decimal place.
