• Using Dimensional Analysis
• STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Step-by-step explanation:

Step 1: Define

0.07 mol Ne (g)

Step 2: Identify Conversions

STP - 22.4 L per mole

Step 3: Convert

1. Set up:
   `\displaystyle 0.07 \ mol \ Ne((22.4 \ L \ Ne)/(1 \ mol \ Ne))`
2. Multiply:
   `\displaystyle 1.568 \ L \ Ne`

Step 4: Check

Follow sig fig rules and round. We are given 1 sig fig.

1.568 L Ne ≈ 2 L Ne
