<span>0.9% glucose solution means there are 0.9 g of glucose per 100 mL water.
</span><span> The concentration is required per litre for molar concentration:
0.9% glucose solution contains 9 g of glucose per 1000 mL or 1 L of water.
Molar mass of glucose is 180.16 g mol^-1 so 9 g = 9g/180.16 g mol^-1 = 0.05 moles
</span><span> 1 L of water contains 0.05 moles of glucose so molar concentration is 0.05 M or 0.05 mol/L </span>
Answer:
11.78 inches
Step-by-step explanation:
The chain travel will equal the length of the 225° arc on the central gear. Arc length (s) is given by the formula ...
s = rθ
where θ is the central angle in radians. We know that 180° is π radians, so the chain travel is ...
s = (3 in)(225°)(π/180°) = 15π/4 in ≈ 11.78 in
