Answer:
<h2>Density = 0.5 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass = 60 g
volume = 120 mL
Substitute the values into the above formula and solve
That's
<h3>We have the final answer as
<h3>Density = 0.5 g/mL</h3>Hope this helps you
The mass of water decomposed to produce 50 g oxygen has been 56.28 g. Thus, option D is correct.
The reaction for the decomposition of water has been:
From the balanced equation, 2 moles of water decomposes to form 1 moles of hydrogen and 1 mole of oxygen.
The mass of oxygen produced has been 50 g. The moles of oxygen has been given by:
The moles of oxygen has been:
The moles of oxygen produced has been 1.5625 mol.
The moles of hydrogen decomposed has been given from the balanced chemical equation as:
The moles of hydrogen decomposes has been 3.125 mol.
The mass of hydrogen decomposed has been given by:
The mass of water decomposed to produce 50 g oxygen has been 56.28 g. Thus, option D is correct.
