Your body uses about 24 grams of Glucose to run cellular respiration. How many molecules does your body need for cellular respir
BartSMP [9]

Answer:

for the cellular respiration the human body needs 1.424 E21 molecules of glucose

Explanation:

mass glucose = 24 g

∴ Mw glucose = 180.156 g/mol

∴ 1 mol ≡ 6.022 E23 molecules

⇒ mol glucose = (24 g)×(mol/180.156 g) = 0.1332 mol glucose

⇒ molecules glucose = (0.1332 mol glucose)×(6.022 E23 molecules/mol)

⇒ molecules glucose = 1.424 E21 molecules

Help!! How many moles of CaCO3 are needed to get 2.35 moles of CaO? What would be my reasoning and evidence?
Fudgin [204]

Equation

CaCO3 ===> CaO + O2

Solution

If you start with this equation, then the balance numbers (molar ratios) are

  • 1 for the CaCO3
  • 1 for the CaO
  • 1 for the O2

If you want 2.35 moles of CaO then you are going to have to start out with 2.35 moles of CaCO3
