One mole of citric acid equals 192.123 g. This number is obtained by adding up the atomic masses of each of the elements that make up citric acid. Since the molecular formual of citric acid is C6H8O7 , its molar mass is obtained by multiplying 6 times the Atomic Mass of Carbon + 8 times the atomic mass of Hydrogen + 7 times the atomic mass of oxygen. You have to multiply by the 6, 8, and 7 because these numbers tell us how many atoms of each of these elements make up the compound.

How do you prepare 1N citric acid?
To make 1 N acetic acid dissolve 1 mole of pure acetic acid in water and dilute it to 1.000 L. There are 2 methods you can use to make the 1 N acetic acid solution, by weight, and by volume. Molar mass acetic acid = 60.05 g/mol Weigh out 60.05 g acetic acid and add to a 1.000 L flask. Then dilute the acetic acid to the 1.000 L mark in a 1.000 L volumetric flask using distilled or deionized water.
What is the percentage of citric acid in grapes?
The percentage of citric acid in grapes is typically around 0.03-0.08%.
Does a lemon have more citric acid than an orange?
The concentrations of citric acid in citrus fruits range from .005 mol/L for oranges and grapefruits to .030 mol/L in lemons and limes. These values will vary depending on the circumstances in which the fruit was grown. welll actually they sometimes do. it depends where they grew from. bananas

How do prepare 0.1M citric acid?
To prepare a 0.1M citric acid solution, measure out the appropriate amount of citric acid powder using a balance, dissolve it in the desired volume of water (usually in a volumetric flask), and mix well until fully dissolved. Finally, adjust the volume to the desired final volume with water, as needed.

What concentration of citric acid is in orange juice?
Citric acid is contained in a variety of other fruits including most notably lemons and limes. Not to mention the fact that it can be found in an independent state. In order to answer this question you would have to know how much citric acid was in all of the fruits that do contain it and how much existed in other foods and in a separate state. I would be suprised if more than 1% of the world's supply of citric acid was found in Oranges. But, to be sure, in order to answer your question one must first, at the very least, know how much citric acid oranges have in them. Maybe you should try asking that question.
What are the chemical properties of citric acid?
Citric acid: (1,2,3-tricarboxy-propan-2-ol) 'tricarboxylic hydroxy-propane acid', weak,up to 8% in citric juices. (0.005 mol/L for oranges and grapefruits to 0.30 mol/L in lemons and limes)pH in lemons < 2Chemical formula: C6H8O7Molar mass 192.1 g/molpKa1=3.15 pKa2=4.77pKa3=6.40Melting point 153oC
What does citric acid and bicarbonate soda do to fizz?
Gives it a tangy taste.More Details: Citric acid is a weak organic acid. It is a natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. Inbiochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of virtually all living things. It can also be used as an environmentally benign cleaning agent.Citric acid exists in greater than trace amounts in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g/L in the juices[3]). The concentrations of citric acid in citrus fruits range from 0.005 mol/L for oranges and grapefruits to 0.30 mol/L in lemons and limes. Within species these values vary depending on the cultivar and the circumstances in which the fruit was grown.For More Check My Profile- theScienceIsAwsome
What acids are found in natural acids?
If you mean NATURAL as in ORGANIC then there are many Citric Acid - oranges, lemon Tartaric Acid - Grapes Ascorbic Acid - Citrus Fruits, Black Current Methanoic Acid - Nettle Sting Organic means 0 comes from nature organically, FROM PLANTS AND ANIMALS
What is the normality of concentrated sulfuric acid?
Concentrated sulfuric acid typically has a normality of around 18-19 N (normal). This high normality is due to the high concentration of sulfuric acid molecules in the solution, which results in a greater number of equivalents per liter compared to dilute solutions.
Specific gravity equals 1.84 gram per milliliters and assay equals 97 percent How many milliliters of concentrated H2SO4 are required to prepare 10 L of 0.1 N H2SO4?
0.1 N means you have a hydronium ion concentration of 0.1 mole/L. Since sulfuric acid is a diprotic acid, you get 2 moles of ionizable protons per mole a sulfuric acid. Meaning, you only need a concentration of 0.05 M sulfuric acid to obtain 0.1 N sulfuric acid. [10 L] * [0.1 mole H+/L] * [1 mole H2SO4/2 mole H+] * [98.08 g/mole H2SO4] * [1 mL/1.84 g H2SO4] = 26.65 mL H2SO4 required to make 10 L 0.1 N H2SO4.
