Calculate the number of moles present in 160 gm of NaOH. [Atomic Mass : Na = 23, H = 1, O = 16]

Explanation

To calculate the number of moles present in 160 grams of NaOH, we can follow these steps:

### Step 1: Understand the formula for calculating moles
The formula to calculate the number of moles (n) is given by:
\[ n = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]

### Step 2: Identify the given mass
From the question, we know that the given mass of NaOH is:
