The half life of first order decomposition of nitramide is 2.0 hour at `15^@C`.
`NH_2NO_2(aq) to N_2O(g) + H_2O(l)` If 6.2 gm of `NH_2NO_2` is allowed to decompose, find :
time taken for nitramide to decompose 99%

Explanation

To solve the problem of determining the time taken for 99% decomposition of nitramide (NH₂NO₂), we will follow these steps:

### Step 1: Identify the given data
- Half-life (t₁/₂) of the reaction = 2.0 hours
- Reaction: NH₂NO₂(aq) → N₂O(g) + H₂O(l)
- We need to find the time taken for 99% decomposition.

### Step 2: Calculate the rate constant (k)
