Taking rust to be Fe2O3, you would have the following reaction:Fe2O3 + 6HCl ==> 2FeCl3 + 3H2O
100 g Fe2O3 x 1 mole Fe2O3/159.7 g = 0.626 moles Fe2O3
moles HCl needed = 0.626 moles Fe2O3 x 6 moles HCl/mole Fe2O3 = 3.76 moles HCl needed
Mass HCl needed = 3.76 moles HCl x 36.5 g/mole = 137 g HCl needed

What has more atoms 17.031 grams of ammonia or 72.922 grams of hydrogen chloride?
Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.
How does combining hydrogen and oxygen to create water relate to the law of conservation of mass?
The mass of the oxygen and hydrogen that react to form water will be exactly equal to the mass of the water produced.
If potassium has a mass of 39.1 amu and chloride has a mass of 35.45 amu which is the mass of potassium chloride when these two ions are combined?
The molar mass of potassium chloride is 74,5513.
Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The hydrogen molecule, H2, contains two hydrogen atoms and thus, has twice the mass of a single hydrogen atom.
Which element has the lowest mass on the periodic table?
The atom that has the lowest mass is hydrogen. So assuming the same numbers of atoms in each element, hydrogen would be the element with the lowest mass.
What has more atoms 17.031 grams of ammonia or 72.922 grams of hydrogen chloride?
Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.
Nitrogen and hydrogen react to form ammonia. If you react 45 g of nitrogen with 30 g of hydrogen, what will the mass be at the end Include unites?
yes
Why doesn't 1 gram of hydrogen react with 1 gram of chlorine?
One atom of hydrogen reacts with one atom of chlorine forming one molecule of hydrogen chloride (hydrochloric acid). An atom of hydrogen has less mass than one of chlorine so 1 gram of hydrogen contains more hydrogen atoms than one gram of chlorine.
How does combining hydrogen and oxygen to create water relate to the law of conservation of mass?
The mass of the oxygen and hydrogen that react to form water will be exactly equal to the mass of the water produced.
What mass of silver nitrate is needed to fully react with 10.0 grams of calcium chloride?
The mass of silver nitrate is 30,6 g.
How do you make sodium chloride from its elements?
The percentage of sodium in sodium chloride is 39,665 83 %. Mass of NaCl = Mass of sodium X 2,51
What is the mass of 1.26 moles of hydrochloric acid?
1,26 moles hydrogen chloride (not hydrochloric acid) is 45,94 g.
Why do the masses stay the same when you mix sodium bicarbonate and calcium chloride?
Calcium Chloride is a complete salt.There are no replaceble H+ or OH-.So it does not react with NaHCO3.So there is no change of mass.
What mass of silver nitrate will react with 5.85 g of sodium chloride to produce 14.35 g of silver chloride and 8.5 g of sodium nitrate if the law of conservation of mass is true?
14.35 g + 8.5 g - 5.85 g or 17 g.
If potassium has a mass of 39.1 amu and chloride has a mass of 35.45 amu which is the mass of potassium chloride when these two ions are combined?
The molar mass of potassium chloride is 74,5513.
Sodium chloride molar mass?
The molar mass of sodium chloride is 58,44.
How many grams of hydrogen chloride can be produced from 0.490 g of hydrogen and 50.0 g of chlorine?
The Atomic Mass of hydrogen is 1.008 and that for chlorine is 35.45. The moles of hydrogen available are therefore 0.490/1.008 = 0.486 and the moles of chlorine available, 50/35.45, are greater than 1. Each molecule of hydrogen chloride requires one atom each of chlorine and hydrogen. Therefore, with the specified conditions, hydrogen is stoichiometrically limiting, and 0.486 moles of HCl can be made.
