How many moles of atoms are present in 154 g of HCl?
Divide by molar mass and check the units(italicalized):0.140 (g HCl) / 36.45 (g.mol-1HCl) = 3.84*10-3 mol HCl
How many molecules are there in 3.46 kg hydrochloric acid?
Mass of HCL given=3.46kgs = 3460 grams of HCL No. of moles of HCL=Mass of HCL provided/Atomic mass of HCL=3460/36.5=94.8 moles no. of molecules=no. of moles x Avogadro number=94.8 x 6.022 x 1023 =57 x 1024 molecules.
Is HCl bent or linear?
It is a di atomic molecule. They are always linear
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
The simplest atomic ratio of the elements present in a compound?
The simplest is 1, as in in HCl and many others.

What is the atomic number of hcl?
Atomic number is a property of an atom (An Element) and not a chemical compound. Sodium chloride is a compound and thus it can not have any atomic number. Atomic number is the number of protons present in the nucleus of the atom of an element. e.g. Carbon has six protons in its nucleus, therefore its atomic number is six. However, sodium chloride has two different elements as its constituents and therefore one can not determine its atomic number.
What is atomic no of hydrochloric acid?
hydrochloric acid does not have an atomic number. Only elements have atomic numbers and hydrochloric acid is a compound composed of two non-metal elements: hydrogen and chlorine, as you might have guessed by the name. However: Hydrogen's atomic number is 1 and Chlorine's atomic number is 17

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.
Is HCl bent or linear?
It is a di atomic molecule. They are always linear
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?
What is the number of neutrons in an atomic number?
Subtract the atomic number from the atomic weight.
