The molar (molecular) mass of hydrochloric acid is found by adding up the atomic masses of both elements in the compound. (appx.)
H= 1.0
Cl= 35.5
HCl= 36.5 grams

∙ 14y agoConcentrated HCl is roughly 12 molar (around 38% w/w). Industrial grade is somewhat less, usually somewhere in the low thirty percent range (about 10-11 molar). You should check the stock bottle for the exact concentration (actually, if you want the exact concentration, you should do a titration to find out what it is, since at high concentrations HCl is somewhat volatile and the actual concentration may be a bit different from the specifications).

What is the molarity of the solution produced when 85.6 g of hydrochloric acid HCl is dissolved in sufficient water to prepare 0.385 L of solution?
Molar mass of HCl = 1 + 35.5 = 36.5 Number of moles of HCl = mass / molar mass = 85.6 / 36.5 = 2.345 moles Molarity = number of moles / Volume = 2.345 / 0.385 = 6.091 M
How many grams of HCl can be prepared from 2.00 mol H2So4 and 150 g NaCl?
2NaCl + H2SO4 ----> 2HCl + Na2SO4 *molar mass of H2SO4 is 98.09g *molar mass of NaCl is 58.44g *molar mass HCl is is 36.46g Moles NaCl = 150 g / 58.44 = 2.56 The ratio between NaCl and H2SO4 is 2 : 1 so NaCl is the limiting reactant We would get 2.56 mol HCl => 2.56 mol x 36.46 g/mol = 93.3 g
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
How do calculate molarity example being calculate molarity of 6.5g of hcl solution per liter solution?
All you have to do is convert the 6.5 g HCl solution into moles, and then plug that value into the molarity formula. If you need help, here are the formulas: # mol = (mass of substance)/(molar mass) - the molar mass is just the molecular mass of the substance expressed in grams :) Molarity (M) = (# mol solute)/(# L solution) - the solute, in this case, is the HCl, and the solution is just one, based on your question Happy Calculating!!!
The molar mass of C3H8O2 is?
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
What is the molecular weight of HCl?
The molar mass of Hydrogen Chloride (HCl) is 36.46 g/mol It is made up of equal parts of Hydrogen (molar mass 1.007) and Chlorine (molar mass 35.453)
What is the molarity of the solution produced when 85.6 g of hydrochloric acid HCl is dissolved in sufficient water to prepare 0.385 L of solution?
Molar mass of HCl = 1 + 35.5 = 36.5 Number of moles of HCl = mass / molar mass = 85.6 / 36.5 = 2.345 moles Molarity = number of moles / Volume = 2.345 / 0.385 = 6.091 M
How many grams of HCl are contained in 4.25mL of a 0.405M aqueous solution of HCl?
M * V = n 0.405 M * 0.00425 ml = 0.00172125 mole of HCl The molar mass of HCl is: 1.007947 + 35.453 = 36.460947 g/mole m = mm * n So the mass in gram is: 36.460947 g/mole * 0.00172125 mole = 0.0628 gram
What is the molar mass of H2CO3?
1.00794 (H) + 126.90447 (I) = 127.91241 g/mol Even though hydrogen is 1p + 1e, adding protons and electrons does not equal the total mass of an element, because we know energy has mass and that is difficult to calculate ( E = mc ^2), although that answer should suffice.
How many grams of HCl can be prepared from 2.00 mol H2So4 and 150 g NaCl?

How many grams of hydrochloric acid are needed to make a solution of 2 molar?
HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
What is a example of concentration involving volume and mass?
1 molar NaCl is 58.5 g of salt ( a mass) per liter (a volume).
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 would you create a two molar solution of HCl?
Get two moles of HCl and add water until the solution is 1 L
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
The mass of a mole of a substance expressed in grams is called a?
molacular mass
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
