The <u>Mole</u> is the SI unit that expresses the amount of substance.
Mole is defined as - The mole is the amount of substance containing the same number of entities as there are in the 12 grams of Carbon - 12.
Mole is denoted by using symbol mol.
Mole = 6.022 x 10²³ elementary entities.
These number of elementary entities in 1 mole is equal to or called as an Avogadro's number. Mole is equal to 6.022 x 10²³ because this number of entity is same as in exactly 12 g of carbon-12.
It is a very important SI unit of measured which is used by the chemists. Moles are used in measuring in small or tiny things such as atoms, molecules and the other tiny particles.

Answer: what is this sorry
B. it means the compound is dissolved in water
The answer for the following problem is explained below.
- <u><em>Therefore 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.</em></u>
Explanation:
Given:
mass of methane = 6.00 × 10^-3 grams
+ 
→ 
+ 
Firstly balance the following equation:
Before balancing the equation:
→ 
After balancing the equation:
→ 
where;
represents methane molecule
represents oxygen molecule
represents carbon dioxide molecule
represents water molecule
+2 → + 2
16 grams of methane → 44 grams of carbon dioxide
6 × 10^-3 grams of methane → ?
= 
= 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.
<u><em>Therefore 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.</em></u>
Answer:
Answer: Chemical change; Chemical property of heat of combustion
Explanation:
A physical change is defined as a change in which there is alteration in shape, size etc. No new substance gets formed in these reactions.
