Answer:
1 9.9
2 4.95
3 12.375
Explanation:
To solve this problem, we basically need to write a balanced chemical equation:
Like all other hydrocarbons, benzene burns in oxygen to yield water and carbon iv oxide as the only products. A balanced chemical equation is given below:
2C6H6(l)+15O2(g)→12CO2(g)+6H2O(g)
Let’s now proceed to answer the questions.
A. Number of moles of carbon iv oxide produced
From the balanced chemical equation, we can see that one mole of benzene yielded 6 moles of carbon iv oxide.
This means 1.65 moles of benzene will yield: 6 * 1.65 = 9.9 moles of CO2
B. From the balanced equation, we can see that one mole of benzene yielded 3 moles of water. Hence, 1.65 moles will yield 1.65 * 3 = 4.95 moles of water
C. To find the number of moles of oxygen consumed, we can see that 2 moles of benzene consumed 15 moles of oxygen. 1.65 moles of benzene would thus consume 1.65 * 15/2moles = 12.375moles of oxygen
Answer:
The answer is
<h2>866.57 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 44.9 cm³
density = 19.3 g/cm³
We have
mass = 19.3 × 44.9
We have the final answer as
<h3>866.57 g</h3>
