Answer:
<h2>The answer is 2.5 mL</h2>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of object = 10.02 g
density = 4.08 g/mL
The volume of the object is
We have the final answer as
<h3>2.5 mL to one decimal place</h3>Hope this helps you
11.375 g ethylene is consumed if 35.0 grams of oxygen is allowed to react and 7.875 ml of water will be produced when the 35.0 grams of oxygen is allowed to react.
<h3>What are moles?</h3>A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
According to the chemical equation for the combustion of ethylene, 5
moles of oxygen are required to react with 2 moles of ethylene, hence
Similarly, 5 moles of oxygen are required as a reactant to produce 2 moles of water, thus
Given that the density of water is , therefore
The volume of water = 7.875 ml
