Question

What mass of O₂ can be generated by the decomposition of 100.0 grams of NaCIO3? 2NACIO3 → 2NaCl + 30₂

A. 30.48 g
B.90.2 g
C.46.2 g
D. 45.1 g​

Answer 1

Answer: D 45.1

Step-by-step explanation:

100/106.441 x(3/2) x (31.9988) = 45.1

106.441 is the molar mass of NaClO3 from the periodic table

31.9988 is the molar mass of O2 from the periodic table
