If you have 730 moles of a gas at 304 Kelvin in a 4.50 Liter container what

vova2212 [387]

Answer:

4046atm

Explanation:

For this question you can use the ideal gas law,

Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.

Because of the units given, R will equal .08026 $P=4046 atm$

<h3>Rearrange the equation to solve for pressure:</h3>

$P=\frac{nRT}{V}$

Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):

$P=\frac{(730)(.08206)(304)}{4.5}$

This will give you:

$P=4046atm$
