The equation for this reaction is shown below. C. H.O.
C. H.O. +
salicylic acid
C. H.O. + CH. COOH
aspirin
Calculate the maximum mass of aspirin that could be made from 2.00 g of
salicylic acid. The relative formula mass (M.) of salicylic acid, C. H.O., is 138
The relative formula mass (M.) of aspirin, C. H.O., is 180

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
