56.5υ
66.5u​

Answer 1

Answer:

58.50 amu.

Step-by-step explanation:

Answer 2

58.50 amu

Because a proper formula is electrically neutral (with no net electrons gained or lost), the ions can be considered atoms for the purpose of calculating the formula mass. To two decimal places, the formula mass of NaCl is 58.44 amu. The formula mass of CaF2 is 78.08 amu.
