Answer:
In order to obtain a volume of
1 L
,
500 mL
of water must be added to the original solution of
500 L
.
Explanation:
Molar mass can be determined by adding the atomic masses of each individual element, depending on how many times they appear. You can find how many times they appear by looking at their respective subscripts. Atomic masses of each element can be found on the periodic table.
For example, in #1
Multiply the mass of Lithium (6.941) by 4, because there are 4 lithium molecules.
Multiple the mass of Phosphorus (30.974) by 2 because there are 2 Phosphorus molecules.
And multiply the mass of oxygen (15.999) by 7 because there are 7 oxygen molecules.
After you have those values, add them together to find the total molar mass of the compound.

Explanation:
In this question, we have to remember that in all combustion reactions we will have <u>Oxygen</u> as reactive (
) and the products are <u>Carbon dioxide</u> (
) and <u>Water</u> (
). Additionally, for the states, we will have (l) for the <u>liquid state</u> and (g) for the <u>gas state</u>. So, we can analyze each reaction:
<u>Part A.</u>
The formula for nonane is
, with this in mind we can write the combustion reaction:

When we balance the reaction we will obtain:

<u>Part B.</u>
The formula for 2-methylbutane is
, with this in mind we can write the combustion reaction:

When we balance the reaction we will obtain:

<u>Part C.</u>
The formula for 3-ethyltoluene is
, with this in mind we can write the combustion reaction:

When we balance the reaction we will obtain:
