Please Help Will Mark Brainliest!!! Ammonia gas has a molar mass of approximately 17 grams per mole. At 290K and 1.2 atm, a sample of ammonia has a volume of 3.7 L.

In three to five sentences, explain how you can find the mass of the ammonia. Then, given R=0.0821L⋅atmmol⋅K, calculate the mass.

3.17 grams.

Explanation:

First of all, you need to explain the formula you are going to use. (This does not count as 1 of your 3 sentences).

The formula is

P*V = n*R*T

You know what P and V are on the left

P = 1.2 atmospheres

V = 3.7 Liters

You are looking for n (mols)

On the right, you know what R and T are. So you take the product of R and T and divide into the product of P and V

When you know n, you can use the molar mass to find the actual mass. You can condense this any way you like. I'm more concerned about your understanding.

P*V = 1.2 * 3.7 = 4.44

R*T = 0.0821 * 290 = 23.809

PV/RT = n

4.44 / 23.809 = 0.1865

1 mole of Ammonia gas = 17 grams

0.1865 mol = x                                    Cross multiply

x = 17 * 0.1865

x = 3.17   grams of Ammonia.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
