There are approximately 0.2 moles of CaCO3 in 20 grams.

## So let us examine the query more closely

The conversion from mass to moles is an essential part of chemistry calculations. To determine the number of moles in a given amount of substance, we need to use the formula:

moles = mass / molar mass

In the case of calcium carbonate, CaCO3, the molar mass is 100.0869 g/mol. Therefore, to find the number of moles in 20 grams of CaCO3, we can use the formula above:

moles = 20 g / 100.0869 g/mol = 0.1998 moles

Rounding off the answer, we get approximately 0.2 moles of CaCO3 in 20 grams.

According to Michael R. Lindeburg, an American mechanical engineer, “all chemical calculations require a knowledge of the chemical formulas involved.” Calcium carbonate’s chemical formula is CaCO3, consisting of one calcium atom, one carbon atom, and three oxygen atoms.

Furthermore, it is interesting to note that calcium carbonate is widely used in various industries, such as construction, agriculture, pharmaceuticals, and food. Additionally, it is the main component of many natural substances, such as chalk, limestone, and marble.

Table:

| Parameter | Calcium Carbonate |

| ———– | —————– |

| Chemical formula | CaCO3 |

| Molar mass | 100.0869 g/mol |

| Common name | Limestone, chalk, marble |

| Usage | Construction, agriculture, pharmaceuticals, food |

In conclusion, we can say that to find the number of moles in a given amount of substance, we need to divide the mass by the molar mass. Calcium carbonate is a widely used compound with many interesting applications, and it is the main component of many natural substances.

Therefore no. of moles = Molecular weightGiven weight=10020 =0. 2 moles.

20 grams of CaCO3 represents 0.2 moles of CaCO3.

mass of CaCO₃ = 20 g, molar mass of CaCO₃ = 100.0869 g/mol. ∴ n = mass/molar mass = (20 g)/ (100.0869 g/mol) = 0.1998 ≅

0.2 mol. So, the right choice is: B. 0.2.

The total number of moles represented by 20 grams of CaCO3 is Answers Answer 1 Moles=CaCo3=20g/100 gm/mol=0.2

## Response to your question in video format

In this video, we learn how to convert moles of CaCO3 to grams. To do this, we need to find the molar mass of CaCO3 by adding the masses of all the individual elements, which we can find on the periodic table. Once we have the molar mass, we can multiply it by the given number of moles of CaCO3 to get the answer in grams. To convert grams back to moles we would simply divide by the molar mass.
