I think the correct answer would be the second option. The volume of 1 mol of gas at standard temperature and pressure would be the same for any gas. If and only if the gas is an ideal gas. This is according to the ideal gas law ( PV = nRT ), at STP ( P = 1 atm T = 273.15 K ) you would calculate the volume of the gas to be 22.4 L. So, 1 mol of any ideal gas would occupy 22.4 L of volume. We calculate as follows:
PV = nRT
V = nRT / P
V = (1 mol ) (0.08205 L-atm / mol K) (273.15 K ) / 1 atm
V = 22.4 L <span />

Answer: The molarity of the malonic acid solution is 0.08335 M
Explanation:
To calculate the molarity of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus the molarity of the malonic acid solution is 0.08335 M
<span>There
are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. Josh should calculate the moles of the sodium nitrate by dividing the mass with the molar mass of sodium nitrate. This is because it is the solute in this problem. </span>
