you need to do what is called a back-titration, by reacting the seashell (ground up very fine) with an acid, then titrating the solution with a base. the data can then be used to find the moles of CaCo3, and from there you can go to grams. Divide grams CaCo3 by the mass of seashell used, then multiply by 100 to find the percentage

What vertebrate group produce eggs with a leathery shell?
Reptiles, such as turtles, snakes, and lizards, produce eggs with a leathery shell. The leathery shell is flexible and allows the eggs to absorb moisture and exchange gases with the environment. Unlike reptiles, birds and some other groups of vertebrates produce eggs with a hard, calcified shell.
Do crocodiles produce amniotic eggs?
Yes. Crocodiles lay their eggs on land, in a hole or mound, depending on the species. The embryo develops inside a yolk-filled amnion with a hard, white calcium shell that softens as the crocodile matures and absorbs the calcium.
What does the egg cell contain?
the gooey little yellow circle thing and the white, but that parts see through, and then theres a really thin transparent lining connected to the shell.
How are egg shells and the enamel of your teeth the same?
Both teeth and eggshells are made of stone-like minerals containing mostly calcium. Bird eggshells are made of calcium carbonate, whil dental enamel is formed from calcium phosphate. Both of these materials are classified as COMPOSITES because they are actually not pure calcium carbonate or phosphate, but also contain additional components that are softer, and allow the mineral-like crystals to bond together into a rigid structure. The precise way the composite is organized, at the microscopic level, determines whether the material is hard and resiliant (like enamel) which is resistant to cracking, or hard and brittle like eggshell that cracks much more easily. To read more about how nature uses different materials, see if you can obtain a copy of the book--- _Life's Devices_, by Steven Vogel, 1988, Princeton University press--- from a local library. Or ask one of the librarians to help you find more information on the subject if the book isn't readily available.
What reaction happens when an egg is soaked in vinegar?
The eggs won't react, it is the vinegar that acts on the egg. The acid in the vinegar will corrode the calcium in the egg shell, causing the egg to become soft, like rubber.
What advantage is their in having eggs with a leather shell?
the advantage of having a leather shell:-protects the egg-Some leathery eggs also have calcium carbonate but much more protein than the average bird egg. This protein is typically keratin, which is the same type of protein that makes up human hair and fingernails.-Leathery eggshells do not necessarily have calcium carbonate. Some types of eggshells have little or no calcium in them at all, and instead are composed primarily of proteins. They may have other substances, such as lipids or some other mineral, as part of their makeup to ensure a solid, flexible shell.-Tough, leathery eggs are generally very similar to hard eggs in structure, but the shell has some differences in its composition. Specifically, hard-shelled bird eggs tend to be a mix of calcium carbonate and protein. The protein helps make the shell smooth and holds it together, while the calcium carbonate gives it its hardness.biology
Why will you need eggs in making an egg bounce with vinegar?
The egg shell is a calcium compound, calcium carbonate. Vinegar contains acetic acid. They react to form calcium acetate and release carbon dioxide, the gas bubbles that you see.
What eggs shell are made of?
The main ingredient in eggshells is calcium carbonate (the same brittle white stuff that chalk, limestone, cave stalactites, sea shells, coral, and pearls are made of). The shell itself is about 95% CaCO3 (which is also the main ingredient in sea shells). The remaining 5% includes calcium phosphate and magnesium carbonate and soluble and insoluble proteins.
What happens to a raw egg if placed in vinegar?
Vinegar dissolves the eggshell. Vinegar contains a chemical named Acetic Acid (about 3% of it is acetic acid), among other things. Egg shells contain calcium carbonate. Calcium carbonate in the egg shell reacts with vinegar to form carbon dioxide (can be seen as bubbles in the vinegar). The reaction is: CaCO3+ 2H+ -> Ca+2 + H2O +CO2
What do you do if they lay soft shell eggs?
Give them calcium supplement.
Why is calcium important in a laying ration?
I assume the question is about hens and eggs? In which case, calcium is needed in a laying ration to help the hen lay eggs with a strong shell.
Other than calcium what nutrients do eggs shells contain?
The nutrient breakdown of an egg shell is as follows Water, Protein, fat, ash, calcium, phosphorus, sodium, magnesium, potassium, sulfur, glutamic acid. Follow the link for a percentage breakdown of these.
What makes the eggs shells color?
it is because egg shell contains calcium and this what makes it white

How does vinegar make the dye stick on the Easter eggs?
The egg shell is basically calcium. Vinegar is a weak acid, and "etches" the calcium egg shell slightly. Since the water is colored, it leaves behind that coloring in the slightly softened surface of the egg shell.
What is the crust of an egg made of?
The generalized eggshell structure, which varies widely among species, is a protein matrix lined with mineral crystals, usually of a calcium compound such as calcium carbonate. It is calcium build-up and is not made of cells. Harder eggs are more mineralized than softer eggs.
Why did a female java dove eat her eggs?
One of the reasons is the bird's Calcium requirement which it tries to get from egg shell.
