What is the density (g/L) of NH3 at 105 kpa and 25 C ( 0.721 g/mol)?

Chemistry

Answer:

0.721 g/L

Explanation:

Ideal gas equation ->PV= nRT   ; n= mass (m)/ molar mass (M);

densitiy= mass (m)/ volume (V)

PV= (m/M)*RT  -> PVM= mRT   -> PM/RT= m/V   -> PM/RT=d

We need to put in SI units

105 Kpa= 1.04 atm

25°C= 298 K

d= (1.04 atm * 17 g/ mol)/(0.0821 * 298 K) = 0.721 g/L

HELP!! b. At the equivalence point, all of the acid has been neutralized by the base. Why does the pH change so
CaHeK987 [17]

At equivalence there is no more HA and no more NaOH, for this particular reaction. So that means we have a beaker of NaA and H2O. The H2O contributes 1 x 10-7 M hydrogen ion and hydroxide ion. But NaA is completely soluble because group 1 ion compounds are always soluble. So NaA breaks apart in water and it just so happens to be in water. So now NaA is broken up. The Na+ doesn't change the pH but the A- does change the pH. Remember that the A anion is from a weak acid. That means it will easily attract a hydrogen ion if one is available. What do you know? The A anion is in a beaker of H+ ions! So the A- will attract H+ and become HA. When this happens, it leaves OH-, creating a basic solution, as shown below.

Answer:

so 0.15 moles X 22.4 dm3/mole=3.36 dm3. Next we find the moles of hexane combusted, and then the moles of CO2. Finally, we find the volume of CO2 using the fact that at STP, 1 mole of gas = 22.4 dm3.
