Answer:
a) moisture content of the flour on a wet basis = 13.272%
moisture content of the flour on a dry basis = 15.303%
b) Density = 509.368 Kg/m³
Explanation:
Given:
Mass of wheat = 74.75 stone
1 stone = 6.35029 kg
thus,
Mass of wheat = 74.75 × 6.35029 kg = 474.68 kg
Water content = 3500.0 moles
Molar mass of water = 18 g/mol
Thus, mass of water = 3500 × 18 = 63000 grams = 63 kg
a) moisture content of the flour on a wet basis
= [tex]\frac{\textup{Mass of water}}{\textup{Total mass of the wheat }}\times100\%[/tex]
= [tex]\frac{\textup{63}}{\textup{474.68}}\times100\%[/tex]
= 13.272%
moisture content of the flour on a dry basis
= [tex]\frac{\textup{Mass of water}}{\textup{Dry mass of the wheat }}\times100\%[/tex]
= [tex]\frac{\textup{63}}{\textup{474.68-63}}\times100\%[/tex]
= 15.303%
b) Total volume of the flour = 4 × 246.2 quarts = 984.8 quarts
also,
1 quarts = 0.000946353 m³
thus,
984.8 quarts = 984.8 × 0.000946353 m³ = 0.9319 m³
Now,
Density = [tex]\frac{\textup{Mass}}{\textup{Volume}}[/tex]
or
Density = [tex]\frac{\textup{474.68}}{\textup{0.9319 }}[/tex]
or
Density = 509.368 Kg/m³
