a) Na2so4

b)AICI3​

Answer 1

Answer:

142.04 g/mol

The formula mass for sodium sulfate was calculated on page T-9. Referring to those numbers, the formula Na2SO4 means: two moles sodium (45.98 g), one mole sulfur (32.06 g), and four moles oxygen (64.00 g) combine to form one mole of sodium sulfate (142.04 g).
