Calculate the density of a substance in pennyweights per peck that has a volume of 0.326 hogsheads and a mass of 55.63 kg. 1 pennyweight = 1.55 grams 1 hogshead = 238.5 liters 1 peck = 9.091 liters answer is units of pennyweights/peck.

The mass is
m = 55.63 kg = 55630 g 
Because 1 pennyweight = 1.55 g, therefore
m = 55630/1.55 = 35890.32 pennyweights.

The volume is 
V = 0.326 hogsheads.
Because 1 hogshead = 238.5 L, therefore
V = 0.326*238.5 = 77.751 L
Because 1 peck = 9.091 L, therefore
V = 77.751/9.091 = 8.5525 pecks

The density is
ρ = m/V
   = (35890.32 pennyweights) / (8.5525 pecks)
   = 4196.5 pennyweights/peck

  4196.5 pennyweights/peck.

Ihave, but this question is gonna probably get deleted.
