Answer:
NH₃ = 17.03 g/mol
Explanation:
Molecular weight is calculated by adding the atomic mases of all the atoms present in a molecule.
Like in case ammonia three hydrogen atoms and one nitrogen atom are present.
1 H = 1.01 g/mol
1 N = 14 g/mol
NH₃ = 14 + (1.01×3)
NH₃ = 17.03 g/mol
Solid (ice caps)
Liquid (oceans, rivers, lakes, etc)
Gas (clouds)
Half-life is the amount of time, in days or years( most common) a certain substance disintegrate half of it's content.
We are given the initial (Ao) and final (A) amount of the substance. The time passed (T) is also given and we are asked to find the half-life (t). We use the equation below:
A=Aoe^(-ln2/t)T
25=200e^(-ln2/t)(11.46)
Solve for t
Answer: 3.82 days
