Convert 277.3 mL at 50 mmHg to its new volume at 152 mmHg.
worty [1.4K]

Answer:

D. 91.22 mL

Explanation:

Boyle's Law P₁V₁ = P₂V₂

                  (50mmHg)(277.3mL) = (152mmHg)(V₂)

                  V₂ = 13865/152mmHg

                  V₂ = 91.2170526 mL = 91.22 mL

Using 25 micromoles, pmoles, of CO2 consumed how many grams of glucose (MW = 180 g/mole) were produced?
Sladkaya [172]

Grams of glucose = 0.7488 mg=748.8 μg

<h3>Further explanation</h3>

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
