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 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 solute are in 50 mL of a 12 M HCl solution?
To find the number of moles of solute in the solution, first, calculate the amount of HCl in grams using the formula: moles = molarity x volume (in liters). Then, convert the grams of HCl to moles by dividing by the molar mass of HCl (36.46 g/mol).
How many moles are present in a sample of HCl with a mass of 3.65?
0.1mol
How many moles of HCl are on 10 grams of substance?
To find the number of moles, you need to divide the given mass (10 grams) by the molar mass of HCl (36.46 g/mol). This will give you approximately 0.274 moles of HCl.
How many moles are in 67.4 g of HCI?
67,4 g HCl is equivalent to 1,85 moles.

How do you convert 65.0 g HCl to moles?
To convert grams of a substance to moles, you need to divide the given mass by the molar mass of the substance. The molar mass of HCl (hydrochloric acid) is 36.46 g/mol. Therefore, 65.0 g of HCl is equivalent to 65.0 g / 36.46 g/mol = 1.78 moles of HCl.
How many grams are in 0.25 moles HCl?
To convert moles to grams, you need to know the molar mass of the substance. The molar mass of HCl is approximately 36.46 g/mol. Therefore, 0.25 moles of HCl would be equivalent to 9.115 grams (0.25 moles x 36.46 g/mol).
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 are in 291.68 grams of hydrochloric acid?
To calculate moles of HCl in 291.68 grams, use the molar mass of HCl which is 1 + 35.5 = 36.5g/mole. 291.68 g x 1 mol/36.5 g = 7.99 moles HCl (3 sig figs)
A solution contains 72.0 g of HCl and 468 g of (C6H6). What is the mole fraction of benzene?
First, calculate the moles of each component: moles of HCl = 72.0 g / molar mass of HCl and moles of C6H6 = 468 g / molar mass of C6H6. Then, calculate the total moles in the solution by adding the moles of each component. Finally, calculate the mole fraction of benzene by dividing the moles of C6H6 by the total moles in the solution.
