# How can I find the volume of 3.0 x 10(25) molecules of Neon gas at STP?

##### 2 Answers

The answer is

In order to determine the volume of **STP**, you need to know that at **STP** (standard temperature and pressure), **mole** of any ideal gas occupies exactly

We must however find out how many moles of **mole** of a substance.

**moles**; this means that **molecules** make up

We can now find out the volume by using

You can determine the volume of

**Convert molecules of Neon to moles.**

(I'm leaving some guard units to reduce rounding errors.)

**Given/Known:**

P = 1 atm

n = 49.82 moles

R =

T =

**Unknown:**

Volume

**Equation:**

**Solution:**

Divide both sides of the equation by P. Solve for V.

(The answer is rounded to two significant figures because

**Answer:**

The volume of **STP** is
