Using 25 micromoles, pmoles, of CO2 consumed how many grams of glucose (MW = 180 g/mole) were produced? Convert your answer to milligrams (mg):
and to micrograms (ug):

Grams of glucose = 0.7488 mg=748.8 μg

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 :

mass of glucose

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
