What is the gram molecular weight of Sodium hydroxide if its molecular mass is 40 a.m.u?
The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.
What is the gram atomic mass?
The gram atomic mass, also known as molar mass, is the mass of one mole of an element or a compound in grams. It is numerically equal to the atomic or molecular weight of the substance in atomic mass units.
Molecular mass equals 2vapour density?
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
What is the molecular mass of hydrogen?
For H2 (natural occurring element Hydrogen) it is 2*1.00794 a.m.u = 2.01588 a.m.eThis means that 1.00000 mole H2 has a mass of 2.01588 grams
What is the molecular mass of hydrogen sulphide H2S?
The molecular mass of hydrogen sulfide (H2S) is 34.08 grams per mole.
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.
What is a gram of a molecular substance?
A gram of a molecular substance is the quantity that will have a mass of 1 gram.

What is the gram ayomic mass of hydrogen?
The gram atomic mass of hydrogen is 1.008.
What is the gram atomic mass?
The gram atomic mass, also known as molar mass, is the mass of one mole of an element or a compound in grams. It is numerically equal to the atomic or molecular weight of the substance in atomic mass units.
The molecular mass of glucose is 180. this means that 180g of glucose contain?
The gram molecular mass of glucose is 180 gram. Reason. The atomicity of glucose is 24.

What is the number of grams of hydrogen gas produces when 146 grams of HCL decompose completely?
The gram molecular mass of HCl is 36.46 and the gram atomic mass of hydrogen atoms is 1.008. Therefore 146 grams of HCl decompose to provide 146(1.008/36.46) or about 4.04 grams of hydrogen gas, to the justified number of significant digits.
What is the method of working out the molecular mass of hydrogen?
On the periodic table it says that one mole of hydrogen atoms weighs 1.008 grams. However, Hydrogen is a diatomic molecule (it is composed of two hydrogen atoms in its molecular state). Hence, the molecular mass of hydrogen is 1.008 multiplied by 2 = 2.016g this is the mass of one mole of hydrogen. Hope this helps!
What is the molecular mass of hydrogen sulphide H2S?
The molecular mass of hydrogen sulfide (H2S) is 34.08 grams per mole.
What is the gram molecular mass of phosphorous?
The atomic mass of phosphurus is 31. The atomic mass of chlorine is 35.5. Therefore, the gram molecular mass of PCl3 is 31+3x35.5=137.5 grams per mole.
