Homework Answers

Answer #1

16)--b is correct because molarity is the moles of solute divided by litres of solution .So 0.5/0.15=3.3M.

17)-option c is correct because firstly we convert 120mls into 120 litre.120mls=0.12L.So 0.289/0.12=2.41M.

18)-option d is correct because firstly we convert 63 gram of NaCl into moles.63g =1.078moles.So 1.078moles/0.65L=1.7M.

20)-option d is correct because it is last stage (hardening).

21)- option e is correct because auxin initiate root formation.

22)--option a is correct because explant inoculate on media for proper growth.

23)-option b is correct because cytokinin initiate shoot formation.

24)-option c is correct because this is the first stage in which we check mother plant.
