Answer:
The mass of O2 is [18 moles × 32 g/mol] = 576 grams. Overall, 12 moles of NaClO3 will produce 576 grams of O2.

Answer:
4F
Explanation:
F= weight in gram of substance / equivalent weight of a substance
( equivalent weight of a substance = molar mass/ n factor)
n factor = 2
therefore,
F= 245/(122.5/2)
F= 245*2/122.5
F= 245/61.25
F=4
