The  moles    of  ammonia  in  1.20  x10^25  molecules  of  ammonia  is  calculated  as  follows

by  use   of   Avogadro    constant

1moles =  6.02  x10^23

what  about    1.20  x10^25  moles

by  use  of  cross  multiplication

=   1 mole   x  (  1.20  x10^25)  /(   6.02  x10^23)   =  19.93  moles

Calculate the mass of butane needed to produce 97.4 g of carbon dioxide. Express your answer to three significant figures and in
Vsevolod [243]

Answer:

32.1 g

Explanation:

Step 1: Write the balanced combustion reaction

C₄H₁₀ + 6.5 O₂ ⇒ 4 CO₂ + 5 H₂O

Step 2: Calculate the moles corresponding to 97.4 g of CO₂

The molar mass of CO₂ is 44.01 g/mol.

97.4 g × 1 mol/44.01 g = 2.21 mol

Step 3: Calculate the moles of butane that produced 2.21 moles of carbon dioxide

The molar ratio of C₄H₁₀ to CO₂ is 1:4. The moles of C₄H₁₀ required are 1/4 × 2.21 mol = 0.553 mol

Step 4: Calculate the mass corresponding to 0.553 moles of C₄H₁₀

The molar mass of C₄H₁₀ is 58.12 g/mol.

0.553 mol × 58.12 g/mol = 32.1 g

GaryK [48]

Answer:

The balanced equation for methanol when is burned in the air, is

CH3OH + O2 ----->  3/2 CO2  +2 H2O and as you see coefficient of oxygen is 3/2

Explanation:

When you always burn something you are doing combustion. The reactives are your compound + O2, and as products you have CO2 and H2O
