When the amount of oxygen is limited, carbon and oxygen react to form carbon monoxide. How many grams of CO can be formed from 3
Alinara [238K]

<u>61.25 grams</u> of CO can be formed from 35 grams of oxygen.

The molecular mass of oxygen is <u>16 gmol⁻¹</u>

The molecular mass of carbon monoxide is<u> 28 gmol⁻¹</u>

Explanation:

The molar mass of carbon monoxide is molar mass of C added to that of O;

12 + 16 = 28

= 28g/mol

The molar mass of oxygen is 16 g/mol while that of oxygen gas (O₂) is 32 g/mol

Since the ration oxygen to carbon monoxide is 1: 2 moles, we begin to find out how many moles of carbon monoxide are formed by 35 g of oxygen;

35/32 * 2

= 70/32 moles

Then multiply by the molar mass of carbon monoxide;

70/32 * 28

= 61.25 g

Wine goes bad soon after opening because the ethanol CH3CH2OH dissolved in it reacts with oxygen O2 gas to form water and aqueou
bagirrra123 [75]

Answer:

We need 0.095 moles of ethanol

Explanation:

Step 1: Data given

Number of moles water = 0.095 moles

Step 2: The balanced equation

CH3CH2OH + O2 ⇒ H2O + CH3COOH

Step 3: Calculate moles of ethanol

For 1 mol ethanol we need 1 mol oxygen to produce 1 mol water and 1 mol acetic acid

For 0.095 moles water, we need 0.095 moles ethanol and 0.095 moles  oxygen

We need 0.095 moles of ethanol
