Answer:
D. The volume of the solvent used was less than 5 liters.
Explanation:
- We have the rule: the no. of moles before dilution equal the no. of moles after dilution.
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 10.0 M, V before dilution = V of stock = ??? L.
M after dilution = 1.0 M, V after dilution = 5.0 L.
<em>V before dilution = V of stock = (MV) after dilution/M before dilution</em> = (1.0 M)(5.0 L)/(10.0 M) = <em>0.5 L.</em>
∴ The volume of the stock used is 0.5 L.
The volume of the solvent used is 4.5 L.
<em>D. The volume of the solvent used was less than 5 liters.</em>
The number of moles of hydrogen is equal to the number of moles of nitrogen.
According to the ideal gas equation
PV = nRT
where
- P = the pressure of the gas
- V = the volume of gas
- n = the total amount of ideal gas (moles)
- R = the universal gas constant
- T = the temperature
In the problems there are two identical cylinders means, V₁ = V₂
The pressure inside each of two identical cylinders is equal to atmospheric pressure means, P₁ = P₂
Both gases are at the same temperature, means T₁ = T₂


n₁ = n₂
So the total amount of hydrogen gas is equal to total amount of ideal nitrogen gas.
