How many moles are in 2 grams of HCL?
To find the number of moles in 2 grams of HCl, you need to divide the mass by the molar mass of HCl. The molar mass of HCl is approximately 36.46 g/mol. Therefore, 2 grams of HCl is equal to 2/36.46 = 0.055 moles.
How many moles of HCL are there in 108 grams of the substance?
To find the number of moles in 108 grams of HCl, you need to know the molar mass of HCl, which is about 36.5 g/mol. You can then use this molar mass to calculate the number of moles by dividing the given mass by the molar mass. In this case, 108 grams divided by 36.5 g/mol gives you about 2.96 moles of HCl.
How many moles HCl in 8.3 g HCl?
8.3 grams HCl (1 mole HCl/36.458 grams) = 0.23 moles HCl ------------------------
How would you create a two molar solution of HCl?
To create a two molar solution of HCl, you would need to dissolve 73.0 grams of hydrochloric acid (HCl) in enough water to make 1 liter of solution. This would give you a 2 molar (2M) solution of HCl. Be sure to wear appropriate safety gear and handle the acid with caution.
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

What is the molariy of concentrated HCl?
Concentrated HCl is typically 36.5% industrially. It is thus almost exactly 10 Molar.

What mass of hcl is consumed by the reaction of 2.50 moles of magnesium in equation mg plus hcl equals mgcl2 plus h2?
The balanced chemical equation is: Mg + 2HCl → MgCl2 + H2. Since magnesium reacts with 2 moles of HCl to produce 1 mole of hydrogen, the molar ratio is 2:1. Therefore, with 2.50 moles of magnesium, 5.00 moles of HCl will be consumed. To find the mass of HCl consumed, use the molar mass of HCl (molar mass of HCl = 36.46 g/mol) and the number of moles consumed in the reaction. Thus, the mass of HCl consumed will be 182.3 g.
How many moles of atoms are present in 154 g of HCl?

Why concentration of Hcl is 12 molar?
The concentration of HCl is 12 molar because it means there are 12 moles of HCl present in 1 liter of solution. This concentration is high compared to typical dilute solutions and is usually used for laboratory or industrial applications that require strong acid solutions.
How many moles are present in a sample of HCl with a mass of 3.65?
0.1mol
What is the percentage concentration of a 0.1N HCl solution?
A 0.1N (Normal) HCl solution is equivalent to a 0.1M (Molar) concentration of HCl. This means that there is 0.1 moles of HCl per liter of solution. So, the percentage concentration of a 0.1N HCl solution would be 0.1%.
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
How many moles are in 23.34 grams of h c l?
To find the number of moles in 23.34 grams of HCl, you need to divide the mass by the molar mass of HCl. Calculate the molar mass of HCl (hydrochloric acid), which is 1 (hydrogen) + 35.5 (chlorine) = 36.5 g/mol. Divide the mass of 23.34 grams by the molar mass of 36.5 g/mol to find the number of moles.
