Answer:
5.158 mol/L
Explanation:
To find the molarity, you need to use the formula:
Molarity (M) = moles / volume (L)
You have been grams sodium carbonate. You need to (1) convert grams Na₂CO₃ to moles (via molar mass), then (2) convert moles Na₂CO₃ to moles HCl (via mole-to-mole ratio from equation), then (3) convert mL to L (by dividing by 1,000), and then (4) use the molarity equation.
<u>Steps 1 - 2:</u>
2 HCl + 1 Na₂CO₃ ----> 2 NaCl + H₂O + CO₂
6.5287 g Na₂CO₃ 1 mole 2 moles HCl
-------------------------- x ------------- x ------------------------- = 0.12318 mole HCl
106 g 1 mole Na₂CO₃
<u>Step 3:</u>
23.88 mL / 1,000 = 0.02388 L
<u>Step 4:</u>
Molarity = moles / volume
Molarity = 0.12318 mole / 0.02388 L
Molarity = 5.158 mole/L
**mole/L is equal to M**
This question can be easily confused with. During the early times, organic compound are directly associated with living beings, people, plants and animals. That is somewhat true. The definition of organic compounds are compounds that contain carbon. So, it is true that most of the compounds in our body are organic. But you may confuse it to the abundance of elements in the body, which is oxygen. However, the most abundant element, besides carbon, in organic compounds is Hydrogen. You will notice this obviously in the organic compounds like alkanes, alkenes, alkynes, carbohydrates, lipids, hormones and proteins. Their general chemical formula usually involves Carbon and Hydrogen.
