Answer:

b. 23.3g

Explanation:

Based on the reaction:

CH₄ + 2O₂ → CO₂ + 2H₂O

To find the mass of CO2 produced we must find, as first, the limiting reactant. With limiting reactant we can find the moles and the mass of CO2 as follows:

<em>Limiting reactant:</em>

For a complete reaction of 0.53 moles of CH4 are necessaries:

0.53 moles CH4 * (2mol O2 / 1mol CH4) = 1.06 moles O2.

As there are 1.5 moles, CH4 is limiting reactant.

<em>Moles CO2:</em>

1 mole of CH4 produce 1 mole of CO2. That means the moles of CO2 formed are 0.53 moles.

<em>Mass CO2 (Molar mass: 44.01g/mol)</em>

0.53 moles CO2 * (44.01g / mol) =

b. 23.3g

If 3.64g of sand is separated from 5.25g of a mixture of salt and sand what is the percentage of sand in the sample
Mashcka [7]
Total weight of the mixture of sand and salt = 5.25 g
Weight of sand separated = 3.64 g
Weight of the salt in the mixture = (5.25 - 3.64) g
                                                   = 1.61 g
Then the percentage of sand in the sample = [(3.64/5.25) * 100] percent
                                                                      = 69.33%
So the percentage of sand in the total mixture of sand and salt is 69.33%.
