Answer:
0.940mol &
0.000301mol respectively.
Explanation:
number of moles = given mass / molar mass
given mass of Nacl = 55g Molar mass = 23 + 35.5
n=m/M = 55g/58.5g/mol = 0.940mol
note- (add the atomic weights of sodium and chlorine to get the molar mass of Nacl.) = 58.5g/mol
similarly, NaCO3 = 23 + 12 + 16*3 = 83g/mol
n=m/M = 0.025g/83g/mol = 3.01 * 10^-4 = 0.000301mol
extra: If you ever get asked to put it in number of particles just use the relation of 1mole = 6.02 * 10^23 particles.
It depends on the system if there are more moles of gas on the left and you increase the pressure the yield of a product will increase as the equilibrium moves to the side with the fewest gas molecules
if the right hand side has more moles of gas and you increase the pressure the yield will decrease as the equilibrium shifts to the left hand side where there are more gas moles
hope that helps
