Calculate the number of moles of NaOH required to remove the `SO_2` from 10 metric tons of atmosphere if the `SO_2` is 0.1% by mass. 1 metric ton = `1.0 xx 10^6 g` .
`2NaOH + SO_2 to Na_2SO_3 + H_2O`

Explanation

To solve the problem of calculating the number of moles of NaOH required to remove SO₂ from 10 metric tons of atmosphere, we will follow these steps:

### Step 1: Convert metric tons to grams
1 metric ton = \(1.0 \times 10^6\) grams. Therefore, 10 metric tons is:
\[ 10 \text{ metric tons} = 10 \times 1.0 \times 10^6 \text{ g} = 10^7 \text{ g} \]
