Question

You need 1.50 moles of ammonia (nh3) for a reaction at stp. what volume of ammonia must you measure? also,how many molecules of nacl are in 23.40 grams nacl?

Answer 1

what volume of ammonia must you measure?

1.50 moles NH3 ( 22.4 L / 1 mole ) = 33.6 L NH3 should be measured

how many molecules of nacl are in 23.40 grams nacl

23.40 g NaCl ( 1 mol / 58.44 g) (6.022 x 10^23 molecules / 1 mol ) = 2.4113 x 10^23 molecules

Hope these answer the questions. Have a nice day.
