Question

Calculate the mass in grams of 3.50 x 106 mol of UF6​

Answer 1

Answer: 647,000 g or 6.47x10^5 g

Step-by-step explanation:

find the molar mass of UF6 which is 352.02g/mol

multiply 3.50x10 ^6 mol by the 352.02 g/mol which gives you 647,106,26 g

round to 3 sig figs gives you 647,000g

3.50x10 ^6 mol UF6 (352.02 g/mol UF6 / 1 mol UF6) = 6.47x10^5 g
