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 HCl in 8.3 g HCl?
8.3 grams HCl (1 mole HCl/36.458 grams) = 0.23 moles 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 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 molarity of a solution of 73 g of HCL in 2 liters of water?
Molarity = moles of solute/Liters of solutionSo, get moles HCl.73 grams HCl (1 mole HCl/36.458)= 2.00 moles HCl---------------------------Molarity = 2.00 moles HCl/2 Liters= 1 M HCl=======

.25 g of zinc reacted with 10 mL of HCl what is the moles of zinc reacted?
*first you set the equation: -(10mL of HCl)(1 mol of HCl)/(22.4 mL of HCl)= .446 mol of HCl *you divide by the volume of HCl which is 22.4 at STP. *Then you will divide that .446 mol of HCl with the mol of Zn, which is 1: -(.446 mol of HCl)( I mol of Zn)/(1 mol of HCl)= .446 mol Zn
How many moles are in 67.4 g of HCI?
67,4 g HCl is equivalent to 1,85 moles.
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.
What is the molarity of a 0.5 solution containing 18.34g of hcl?
To calculate molarity, you need to know the molecular weight of the solute. For HCl (hydrochloric acid), the molecular weight is 36.46 g/mol. First, convert 18.34g of HCl to moles: 18.34g / 36.46 g/mol = 0.503 moles. Then, divide moles by the volume in liters to get the molarity. If the volume is not provided, you cannot determine the molarity.
How many moles are present in a sample of HCl with a mass of 3.65?
0.1mol
What is the molarity of a HCl solution if 2.50 L is needed to react with 12.7 g of Al?
To find the molarity, first calculate the moles of HCl by using the molar mass of Al to convert grams of Al to moles, since HCl and Al react in a 1:1 ratio. Then, divide the moles of HCl by the volume in liters to get the molarity. Molarity = moles of solute / volume of solution in liters.
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.
