Calculate the weight of `MnO_2` required to produce 1.50 L of chlorine at `27^@C` and 1.50 atm pressure according to the following equation:
`MnO_2 + 4HCI to MnCl_2 + 2H_2 O + Cl_2`

Explanation

To solve the problem of calculating the weight of \( \text{MnO}_2 \) required to produce 1.50 L of chlorine gas at \( 27^\circ C \) and 1.50 atm pressure, we will follow these steps:

### Step 1: Convert the temperature to Kelvin
To use the ideal gas law, we need to convert the temperature from Celsius to Kelvin.
\[ T(K) = T(°C) + 273.15 \]
\[
