What is the difference between molecular weight in amu and molecular weight in grams?
The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules. The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.
How many grams are in half a mole of NaCl?
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.Na- 23.0Cl- 35.5NaCl- 58.5 grams in one mole
How many moles of iodine are in one mole?
There is one mole of iodine in one mole. There are 126.90447grams of iodine in one mole. There are also 6.022x1023 atoms in one mole.
What is the molecular weight of 7H2O?
Ah, the molecular weight of 7H2O, or water, is about 126.14 grams per mole. Isn't that just a lovely number? Remember, understanding the molecular weight helps us appreciate the beauty and harmony of chemistry.
What is the mass in grams of one mole of sulfur dioxide SO2?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the atomic mass. Sulfur's atomic mass is 32.064 grams.
Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
What is the weight of one mole of sulfur?
The molecular weight of 1 mole of sulfur is 32 amu or grams.
What is the balance chemical equation for the reaction of one mole of carbonic acid with one mole of potassium hydroxide?
2 KOH + H2CO3 = 2 H2O + K2CO3
Is the molecular weight and equivalent weight of aniline is same?
No, the molecular weight and equivalent weight of aniline are not the same. The molecular weight of aniline (C6H5NH2) is around 93.13 g/mol, while the equivalent weight is calculated based on the number of replaceable hydrogen atoms in the molecule, which for aniline is 46.57 g/equiv.
What is molecular formula of carbonic acid?
The molecular formula of carbonic acid is H2CO3, which consists of one carbon atom, three oxygen atoms, and two hydrogen atoms.
HOW MUCH DOES PENTANE WEIGH?
The molecular weight of pentane is approximately 72.15 grams per mole. So, one mole of pentane weighs 72.15 grams.
What is the normality of 2.4M H2CO3?
These statements may be helpful for answering this question: Normality is equal to the number of equivalent weights of solute per Liter of solution. Molarity is equal to the number of moles of solute per Liter of solution, and to determine the number of moles, you take the weight of the solutes in solution divided by the weight of one of those solute molecule (the molecular weight). How does one relate equivalent weights to moles. The equivalent weight of a compound is equal to its molecular weight divided by its valence. The valence in this context means the same thing as the number of substitutable groups (H+s or OH-s). Carbonic acid is a diprotic acid that dissociates to release 2 ionizable H+ s. So along those lines, a 1 M solution of H2CO3 is equivalent to a 2N solution of H2CO3. If 1 molar H2CO3 = 2N H2CO3 , a 2.4 M H2CO3 with 2 ionizable groups x 2.4, or 4.8N. Sorry if you got my first answer and that confused you, the second answer (4.8) is the correct one. I confused normality with equivalent weight. The equivalent weight of an acid with a valence >1 like H2CO3 (valence = 2) is in fact less than its molecular weight, but the question was about normality, the number of equivalents present in a liter of solution which is not the same as the equivalent weight.
How do you get gram molecular weight?
gram molecular weight = weight of one mole of the substance in grams for example 1 mole of water weighs 1 + 1 + 16 = 18 grams so gram molecularweight of water is 18g
How do you calculate density from molecular weight?
Density can be calculated from molecular weight using the formula density = (molecular weight) / (molar volume). Molar volume is the volume occupied by one mole of the substance and can be calculated using the ideal gas law or experimental data. Dividing the molecular weight by the molar volume gives the density of the substance.
How many pounds-mass (lbm) are equivalent to 1 pound-mole (lbmol)?
One pound-mole (lbmol) is equivalent to the molecular weight of a substance in pounds-mass (lbm).
Is molar mass is mass in grams of one kilogram of any pure substance?
No, molar mass is the mass in grams of one mole of a substance. One mole is equal to the molecular weight of the substance in grams.
How many Co atoms are there in 230 grams of CoCl2?
To answer this question you need the molecular weight of CoCl2. CoCl2 molecular weight is 129.84 g/mole 230g CoCl2 divided by the molecular weight 230 g / 129.84 g/mole = 1.77 moles of CoCl2 Multiply the moles by Avagodro's number 1.77 mole * 6.022 X 1023 molecules/mole = 1.07 X 1024 molecules of CoCl2
