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

The distance from the surface of the earth to the moon is approximately 3.8 * 10 to the 5th km. How many days would a distance l
Alla [95]

Answer:

82 days would take a distance like that, if we drive at 120 mi/h

Explanation:

Distance from Earth to moon is 3.8×10⁵ km

You drive at a speed of 120 mi/h

Let's convert the 120 mi/h to km/h

1 mi = 1.61 km

Then 120 mi . 1.61 km / 1mi = 193.2 km

New velocity is 193.2 km. Therefore,

193.2 km are driven in 1 hour

3.8×10⁵ km woul be driven in (3.8×10⁵ . 1)/ 193.2 = 1966.8 hours

1967 hours . 1 day / 24 hours = 82 days

Ammonium phosphate NH43PO4 is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric a
Nataly_w [17]

Answer:

0.050 mol

Explanation:

The reaction that takes place is:

  • H₃PO₄ + 3NH₃ → (NH₄)₃PO₄

Then we convert 0.050 moles of phosphoric acid into moles of ammonium phosphate, using the stoichiometric coefficients of the reaction:

  • 0.050 mol H₃PO₄ * \frac{1mol(NH_4)_3PO_4}{1molH_3PO_4} = 0.050 mol (NH₄)₃PO₄

Thus, the complete reaction of 0.050 moles of phosphoric acid would produce 0.050 moles of ammonium phosphate.
