# Find out the volume of 6.023*10²² of ammonia at stp?

##### 1 Answer

The volume is 2.271 L.

#### Explanation:

**Method 1. Using the Ideal Gas Law**

We can use the **Ideal Gas Law** to solve this problem.

#color(blue)(bar(ul(|color(white)(a/a)pV = nRTcolor(white)(a/a)|)))" "#

where

#p# is the pressure#V# is the volume#n# is the number of moles#R# is the gas constant#T# is the temperature

We can rearrange the Ideal Gas Law to get

#V = (nRT)/p#

**Step 1. Calculate the moles of ammonia**

**Step 2. Calculate the volume at STP**

Remember that STP is defined as 0 °C and 1 bar.

**Method 2. Using the molar volume**

We know that there are 0.100 02 mol of

We also know that the molar volume of a gas is 22.71 L at STP.

∴
