7.4x10^23 = molecules of silver nitrate sample
6.022x10^23 number of molecules per mole (Avogadro's number)
Divide molecules of AgNO3 by # of molecules per mol
7.4/6.022 = 1.229 mols AgNO3 (Sig Figs would put this at 1.3)
(I leave off the x10^23 because they both will divide out)
Use your periodic table to find the molar weight of silver nitrate.
107.868(Ag) + 14(N) + 3(16[O]) = 169.868g/mol AgNO3
Now multiply your moles of AgNO3 with your molar weight of AgNO3
1.229mol x 169.868g/mol = 208.767g AgNO3
Let’s say you are a race car driver and you are trying to beat the other racers and then you decide to increase your speed and as you are increasing speed you are also increasing kinetic energy. Hope this helps :)
PV=nRT
You are funding pressure and you have V = 9.45L, n = 1.9 moles, R = gas constant, and T = 228 K
P(9.45L) = (1.9moles)(0.0821)(228K)
Find P
Multiply
9.45P = 35.57
Divide
P = 3.76 L of N
Answer should be 3.76 liters of nitrogen
