35 g of histidine is dissolved in 260 mℓ
mℓ of distilled water to give a solution with a final volume
of 264. mℓ
mℓ. The relative molecular weight of histidine is 155.2. Give answers to at least 3 significant figures.
(a) What is the concentration in %(w/v)?
Answer = %(w/v)
(b) What is the concentration in M ?
Answer = M
(c) What is the concentration in %(w/w)? (Assume that 1 mℓ
mℓ of water weighs 1 g).
Answer = %(w/w)
