Rubber gloves and other chemical resistant protective clothing are necessary when handling concentrated ammonium hydroxide.
<h3 /><h3>Why it is necessary to handle concentrated solution of ammonium hydroxide with care ?</h3>
- Ammonia is an irritant and corrosive to the skin, eyes, respiratory tract and mucous membranes.
- May cause severe chemical burns to the eyes, lungs and skin.
- Skin and respiratory related diseases could be aggravated by exposure.
The extent of injury produced by exposure to ammonia depends on the duration of the exposure, the concentration of the liquid or vapor and the depth of inhalation.
Hence, Rubber gloves and other chemical resistant protective clothing are necessary when handling concentrated ammonium hydroxide.

<u>Answer:</u> The molar mass of unknown gas is 367.12 g/mol
<u>Explanation:</u>
Rate of a gas is defined as the amount of gas displaced in a given amount of time.

To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

So,

We are given:
Volume of unknown gas (X) = 1.0 L
Volume of oxygen gas = 1.0 L
Time taken by unknown gas (X) = 105 seconds
Time taken by oxygen gas = 31 seconds
Molar mass of oxygen gas = 32 g/mol
Molar mass of unknown gas (X) = ? g/mol
Putting values in above equation, we get:

Hence, the molar mass of unknown gas is 367.12 g/mol
