What is the gram formula mass in NaCL?
The gram formula mass of NaCl (sodium chloride) is approximately 58.44 g/mol. This value is derived from adding the atomic masses of one sodium atom (22.99 g/mol) and one chlorine atom (35.45 g/mol) together.
What is the gram formula for K2SO3?
The gram formula for potassium sulfite (K2SO3) is 158.27 g/mol.
What is the gram formula mass for H2O?
H2O's molar mass is 18 g/mol.
What mass of sodium would make up a 150 gram sample of sodium chloride?
Since each molecule of sodium chloride contains one sodium atom, the mass of the sodium in a 150 gram sample of sodium chloride would be the same as the mass of the sample itself, which is 150 grams.
What is the gram formula mass of acetic acid?
The gram formula mass of acetic acid (CH3COOH) is approximately 60.05 g/mol.

The formula of sodium fluoride is NaF; its gram formula mass is 41.9882.
The formula for sodium carbonate us Na2CO3. Figure the molar mass of sodium carbonate to the nearest gram?
The molar mass of sodium carbonate to the nearest gram is 105,99 g.
What is the mass of 43mol of sodium sulfate?
The gram formula mass of anhydrous sodium sulfate is 142.04. Therefore, 43 gram formula units* of it has a mass of 43(142.04)6.1 X 103 grams, to the justified number of significant digits. _____________________________ For ionic compounds such as sodium sulfate, the term "formula unit" is preferred to "mole".
How many moles are there in 23.376 grams of sodium chloride?
The formula of sodium chloride is NaCl; therefore, the gram formula mass of sodium chloride is the sum of the gram atomic masses of sodium and chloride, or 58.443, to the justified number of significant digits. The number of gram formula masses in 23.376 grams is therefore 23.376/58.443 or 0.399998, to the justified number of significant digits.
What is the gram formula mass in NaCL?
The gram formula mass of NaCl (sodium chloride) is approximately 58.44 g/mol. This value is derived from adding the atomic masses of one sodium atom (22.99 g/mol) and one chlorine atom (35.45 g/mol) together.
What mass of sodium chloride contains 4.59 exp24 formula units?
The gram formula unit mass of sodium chloride is 58.443, and every gram formula unit mass contains Avogadro's Number, 6.022 X 1023 formula units. Therefore, the mass sought is 58.443 X (4.59 X 1024)/(6.022 X 1023) or 445 grams, to the justified number of significant digits.
What is the gram formula for K2SO3?
The gram formula for potassium sulfite (K2SO3) is 158.27 g/mol.
What is the gfm of anhydrous salt?
Based on the category, this answer will refer to sodium chloride, NaCl. Gfm is gram formula mass and is the same thing as molar mass. To find the gram formula mass of NaCl, you add the gram atomic masses (gam) from the periodic table (atomic weights) of the sodium and chlorine atoms in one formula unit. gam Na = 22.99g/mol gam Cl = 35.45g/mol Ggm of NaCl = 22.99g/mol + 35.45g/mol = 58.44g/mol
What is the gram formula mass for H2O?
H2O's molar mass is 18 g/mol.
What mass of sodium would make up a 150 gram sample of sodium chloride?
Since each molecule of sodium chloride contains one sodium atom, the mass of the sodium in a 150 gram sample of sodium chloride would be the same as the mass of the sample itself, which is 150 grams.
Calculate number of grams of sodium in 7.2 grams of sodium phosphate?
The gram atomic mass of sodium is 22.9898, the formula of the least hydrated form of sodium phosphate is Na3PO4.10 H2O, and the gram formula unit mass of this sodium phosphate is 344.09. Therefore, the mass fraction of sodium in this sodium phosphate is 3(22.9898)/344.09 or about 0.20044, and the grams of sodium in 7.2 grams of this sodium phosphate is 1.44 grams of sodium, to the justified number of significant digits.
When you have 46 grams of sodium react with 160 grams of oxygen how many moles of sodium oxide are obtained?
The equation for the reaction is 4 Na + O2 -> 2 Na2O. This shows that, for complete reaction, one mole of oxygen is required for each four gram atomic masses of sodium. The gram atomic mass of sodium is 22.9898; therefore, 46 grams of sodium constitutes 2.00 moles of sodium, to more than the justified number of significant digits. The gram molecular mass of diatomic oxygen is 31.9988; therefore 160 grams of oxygen constitutes 5.000 moles of diatomic oxygen, to more than the justified number of significant digits. This is well over the minimum amount of oxygen required for complete reaction of all the sodium present. Each two gram atomic masses of sodium produces one gram formula mass of sodium oxide; therefore, the number of gram formula masses of sodium oxide produced is 1.00, to at least the justified number of significant digits.
