What is the gram atomic mass?

the relative atomic masses of compounds changed into g grams called the gram atomic mass of that element.for example mass of hydrogen 1.008 gram etc


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 relative atomic mass and how it is related with gram?

when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )


What is the gram formula mass of H2SO4?

The relative atomic masses of sulfur, oxygen and hydrogen are 32, 16 and 1 respectively. The molecular formula of sulfuric acid is H2SO4. Therefore, sulfuric acid has a mass number of 98 g/mol.


How do you convert from molecular mass to grams per mole?

Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.


How many grams of CaCl2 are needed to prepare 2.00 l if 0.700 M CaCl2 solution?

The gram formula mass of CaCl2 is 110.99. By definition, each liter of 0.700 M CaCl2 contains 0.700 gram formula masses of the solute. Therefore, 2.00 liters of such solution contain 1.400 formula masses of the solute, or 155 grams, to the justified number of significant digits.


What is the word equation of calcium with hydrochloric acid?

One gram atomic mass of calcium reacts with two gram molecular masses of hydrochloric acid to form one gram formula mass of calcium chloride and one gram molecular mass of diatomic hydrogen gas.


A compound with the empirical formula SN was found in a subsequent experiment to have a molar mass of 184.32 gmol. What is the molecular formula of the compound?

The empirical formula of SN has a formula unit mass of the sum of the gram atomic masses of nitrogen and sulfur, i.e., about 46.0667. The gram molecular mass given in the problem divided by this formula unit mass is about 4. Therefore, the molecular formula is S4N4.


What is the mass of 4.5 mol of KOH?

Add individual masses (rounded) for gram formula mass.K= 39 O= 16 H= 1 39+16+1= 56Find number of moles = 4.5Multiple gram formula mass and the number of moles56*4.5 = 252g^Answer

How many moles are there in 200 grams of Calcium Carbonate?

For a partly ionically bonded compound such as calcium carbonate, the gram formula mass is substituted for a mole, which technically exists only for purely covalently bonded compounds. The gram formula mass for calcium carbonate is 100.09. Therefore, 200 grams constitutes 200/100.09 or 2.00 gram formula masses of calcium carbonate, to the justified number of significant digits.


When the masses of naturally occurring isotopes of a particular element are averaged the result is called the elements of what?
