MNO₂: 14+(16×2) = 46 g/mol
92/46 = 2
2x NO₂ >>>>>> N₂O₄

Answer:
= 239.311g
Explanation:
atomic mass of C = 12.001g
atomic mass of H = 1.008g
atomic mass of N = 14.0067g
atomic mass of O = 15.99g
Solution:
= 13 (12.001) + 21(1.008) + 14.0067 + 3 (15.99)
= 156 + 21 + 14+ 48
= 239.311g
272.69 grams
This is the answer

Answer:
1. Option A. Beta decay minus 0 -1e
2. Option B. Alpha 4 2He
3. Option A. Beta decay minus 0 -1e
Explanation:
1. 66 29Cu is undergoing beta decay minus since it produces a daughter nuclei having the same mass number and the atomic number increased by 1 i.e 66 30Zn
2. 238 92U is undergoing alpha decay since the daughter nuclei produced has a decrease of 4 in the mass number and a decrease of 2 in the atomic number ie 234 90Th
3. 14 6C is undergoing beta decay minus since the daughter nuclei produced has the same mass number and the atomic number increased by 1 i.e 14 7N
