The molar volume is the volume occupied by 1 mol of any gas at STP.
The molar volume is 22.4 L
The volume occupied by 1.00 mol is 22.4 L
Therefore the volume occupied by 3.00 mol is - 22.4 L x 3 = 67.2 L
The answer is that 3.00 mol of gas particles occupy a volume of -
D. 67.2 L
Answer:
The reaction is not in equilibrium and moves to the left until Q equals Kc.
Explanation:
Hello!
First we must check that the equation is balanced.
We propose the constant Kc for the balanced equation.
We propose Q for the balanced equation.
We calculate the value of Q and compare with Kc
If Q = Kc the reaction is in equilibrium.
If Q> Kc the reaction moves from right to left.
If Q <Kc the reaction shifts from left to right.
We obtain the value of Kc from the value of Kp. If the variation of mol is zero Kp = Kc

<h3>What is Molarity ?</h3>
Molarity (M) is defined as the number of moles of solute dissolved in 1L of solution. Molarity is also known as Molar Concentration. The S.I unit of Molarity is molar (M) or mol/L.
It is expressed as:
Molarity (M) = ![\frac{\text{Number of moles}}{\text{Volume of solution in liters}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BNumber%20of%20moles%7D%7D%7B%5Ctext%7BVolume%20of%20solution%20in%20liters%7D%7D)
Molarity × Volume of solution = Number of moles
As we know that
Number of moles = ![\frac{\text{Given Mass}}{\text{Molar Mass}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BGiven%20Mass%7D%7D%7B%5Ctext%7BMolar%20Mass%7D%7D)
So,
Molarity × Volume of solution = ![\frac{\text{Given Mass}}{\text{Molar Mass}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BGiven%20Mass%7D%7D%7B%5Ctext%7BMolar%20Mass%7D%7D)
Molarity × Volume of solution × Molar Mass = Mass
Volume = ![\frac{150\ mL}{1\ \text{hour}}](https://tex.z-dn.net/?f=%5Cfrac%7B150%5C%20mL%7D%7B1%5C%20%5Ctext%7Bhour%7D%7D)
= 225 mL
Mass of NaCl = Molarity × Volume of solution × Molar Mass
= (0.15 mol/L NaCl) × (58.44 g/mol NaCl) × (225 ml × 0.001)
= 1.97 g NaCl
Thus from the above conclusion we can say that If the patient is given 150 mL/h of IV saline for 1.5 h 1.97 g NaCl she receive.
