What is density?</h3>
- Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass).
- Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density.
Given,
The density of ethanol, C2H5OH = 0.789 g/mL


= 7.843 g

Therefore, the answer is 9.94 ml

<u>The complete question is -</u>
If the density of ethanol, C2H5OH, is 0.789 g/mL. How many milliliters of ethanol are needed to produce 15.0 g of CO2 according to the following chemical equation?
C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(l)
Answer:
You can model a substance doing a Lewis structure
And also you can model it doing a bond-line structure.
The equilibrium state of a gas when it can hold all the molecules of water vapor is known as saturation.
<h3>Which three equilibrium conditions apply?</h3>
A solid substance subjected to three forces with divergent lines of action is in equilibrium if all three of the following three circumstances hold true:
- Coplanar action lines are present (in the same plane)
- The paths of action have come together (they cross at the same point)
- These forces add up to a vector with a total of zero.
<h3>What are equilibrium's first and second conditions?</h3>
An object must satisfy two requirements of equilibrium in order to maintain static equilibrium.
- First, there must be no net force acting on the item.
- Second, there must be no net torque pulling on the object.

Answer:
In this case, ethanol's molecular mass is 46 g/mol. This means that in 1 mol of ethanol, there are 46 g, thus the term molecular mass and molar mass are often used interchangeably. The same is true of a mole. A mole of anything is 6.022 x 1023 of that item

I think its A. because there are nuclear fusion and nuclear fission
