Sodium:
moles = mass/RFM = 8.3/23 = 0.3608..
Chlorine:
moles = mass/RFM = 4.5/71 = 0.06
Ratio of Na to Cl is 2:1
So 0.06 x 2 = 0.12
So we know that the Na is in excess
Now we have to figure out by how much:
Mass = moles x RFM = 0.12 x RFM of 2NaCl = 0.12 x 58.5 = 7.4 (roughly)
Now to figure out by how much do 8.3 + 4.5 = 12.7 and do 12.7 - 7.4 = 5.3 (roughly)
So your answer is A
Shrivel/shrink and become flaccid because the water inside of the potato leaves the potato and joins the salt water due to the lower concentration in the salt water
