If you have 2 grams of acetic acid and 2 grams of sodium bicarbonate do you have the same number of molecules of each compound?
No you do not. The gram-formula mass of sodium bicarbonate is 74, while the mass of acetic acid is 60. If the mass is both 2 grams, the proportion does not work.
(2gNaHCo3/74gNaHCo3) = (2gCH3COOH/60gCH3COOH) is a false statement. One could also use dimensional analysis, but because there were very little conversions, I felt that proportions were easier.
What else can I help you with?
What does the 2 in the chemical formula 2NaHCO3 mean?
The chemical formula for the compound is NaHCO3. If you meant the name of the compound, it's Sodium Bicarbonate, more commonly known as Baking Soda.
If you have three molecules of of sodium bicarbonate?
Three molecules of sodium bicarbonate would consist of three sodium atoms, three bicarbonate ions, and the corresponding number of carbon, hydrogen, and oxygen atoms. Sodium bicarbonate is represented by the chemical formula NaHCO3.
How many molecules are there in 60 g of acetic acid C2H4O2?
The molar mass of acetic acid (C2H4O2) is 60 g/mol. Therefore, there are 1 mole of acetic acid molecules in 60 g. Based on Avogadro's number (6.022 x 10^23 molecules/mol), there are approximately 6.022 x 10^23 molecules in 60 g of acetic acid.
Why is acetic acid in cigarettes?
Acetic acid is in just about everything that is or was alive. It's a very common compound that occurs as a result of a number of important biochemical pathways.
How many molecules are there in 60.0g of acetic acid C2H402?
Find the moles using the formula: moles= grams/molecular mass In this case, molecular mass = 24+4+32 = 60g/mol so 66/60 = 1.1 moles Then, using avogadro's constant, work out the number of molecules. n(molecules) = number of moles x 6.02x10^23 =1.1x 6.02x 10^23 =?
What does number before the compound represent?
The number before a compound indicates the quantity of molecules or atoms present in the compound, based on the subscripts in its chemical formula. It reflects the ratio of elements in the compound and helps determine the stoichiometry of the reaction involving that compound.
How many molecules are in 1 mol of a molecular compound?
It's not entirely clear what you're trying to ask.There can only be one kind of molecule in a compound (otherwise it's a mixture).There can be any number of (identical) molecules in a compound; it just depends on how much of the compound there is.
In a small amount of a compound there may be what of molecules?
In a small amount of a compound, there may be billions to trillions of molecules, depending on the molecular weight of the compound. This number is determined by Avogadro’s number, which is a fundamental constant used to relate the number of particles to the amount of substance.
What does avogadro's number indicate?
It is the number of atoms or molecules of a compound in one mole of that substance.
A compound that has a specific number of water molecules bound to its atoms?
The term for a compound that has a specific number of water molecules bound to its atoms is a hydrate. In a hydrate, water molecules are typically attached to the compound through weak chemical bonds known as hydrogen bonds. The number of water molecules in a hydrate is represented by a numerical prefix in the compound's name, such as in CuSO4•5H2O, where there are five water molecules bound to each copper sulfate molecule.
Is bicarbonate an isotope?
No, bicarbonate is not an isotope. Bicarbonate refers to the chemical compound with the formula HCO₃⁻, which is an anion formed from carbonic acid. An isotope, on the other hand, refers to different forms of the same element that have the same number of protons but different numbers of neutrons. Bicarbonate can contain isotopes of its constituent elements, but it itself is not an isotope.
What is the gram-equivalent weight of sodium bicarbonate?
The gram-equivalent weight of sodium bicarbonate is calculated by dividing the molar mass by the number of equivalents of the compound. For sodium bicarbonate (NaHCO3), the molar mass is approximately 84 grams per mole. Since it has one equivalent of bicarbonate ion (HCO3^-), the gram-equivalent weight of sodium bicarbonate is 84 grams.
