Hello I Need Help On The Question 4 For Chemistry Also This Is A Worksheet For Practice Thank You class=

Sagot :

In order to find the missing pressure of this gas, we need to use the Ideal Gas Law formula, which is a gas law that perfectly correlates each provided information, the formula is:

PV = nRT

Where:

P = pressure

V = volume, 2.0 Liter

n = number of moles, we will find it as well

R = gas constant value, 0.082

T = temperature in kelvin, 30°C = 303 K

To find the number of moles, we need to use the given mass, 10 grams, and the molar mass of CH2O, 30g/mol

30g = 1 mol

10g = x moles

x = 0.33 moles of CH2O in 10 grams

Now we can use the Ideal gas law formula:

P * 2 = 0.33 * 0.082 * 303

2P = 8.19918

P = 4.1 atm is the pressure
