Chemistry

Moles, molarity, and composition

a) How many gmol are there in 21.2 kg of isobutyl succinate(C12H22O4)?
b) If sucrose (C12H22O11) crystals flow into a hopper at a rate of4.5 kg s^-1, how many gram-moles of sucrose are transferred in 30min?
c) A solution of 75 mM tartaric acid (C4H6O6) in water is used as astandard in HPLC analysis. How many
grams of C4H6O6 ·H2O are needed to make up 10 ml of solution?
d) An aqueous solution contains 60 μM salicylaldehyde (C7H6O2) and330 ppm dichloroacetic acid
(C2H2Cl2O2). How many grams of each component are present in 250ml? You can assume the density of
the solution to be same as water, as 1 g/mL (this is an appropriateassumption, since this is a very dilute
solution).
