Answer: The pressure of nitrogen will be 2.0 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.0 atm
V = Volume of gas = 10.0 L
n = number of moles = ?
R = gas constant =
T =temperature =
Now again using ideal gas equation :
Thus pressure of nitrogen will be 2.0 atm

<h2>Solution</h2><em />
<em>Iron</em> is a solid substance at room temperature. You can find the <em>volume</em> of solids (and of not solids) using the density.
You can obtaindthe density of most pure substances in the internet. The density of<em> iron</em> at room temperature is 7.874 g/cm³.
Thus, substituting in the formula, you get:
The answer is rounded to two significant figures because the input, 12g, has two significant figures.
