Question

Using 25 micromoles, pmoles, of CO2 consumed how many grams of glucose (MW = 180 g/mole) were produced?

Answer 1

Grams of glucose = 0.7488 mg=748.8 μg

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

6CO₂+6H₂O⇒C₆H₁₂O₆+6O₂

25 micromoles, μmoles, of CO₂ :

moles CO₂ : moles glucose - C₆H₁₂O₆ = 6 : 1, so :

$\tt moles~glucose=\dfrac{1}{6}\times 25\mu~moles=4.16\mu~moles=4.16\times 10^{-6}~moles$

mass of glucose

$\tt mass=mol\times MW\\\\mass=4.16\times 10^{-6}\times 180\\\\mass=7.488\times 10^{-4}g=0.7488~mg=748.8\mu g$
