Depending a bit on temperature 1.000 L weight 998.0 g at 200C.
Water weights 18.02 grams per mole and putting those together you'll find
that 2.133 L of pure water has 118.1 moles in it.
[ 2.133 (L) * 998 (g/L) / 18.02 (g/mol) = 118.13 mol (verifiable by unit analysis). ]
95,474 moles
1 liter of (liquid) water contains 55.5 moles.
0.0747mol/L of HCL 1.81mol/L of water
4,54 L of CO have 0,182 moles.
0,125 L neon is equivalent to 0,0056 moles.
To find the number of moles of water, you first need to convert the volume (250.0 mL) to liters by dividing by 1000 (since 1 L = 1000 mL). This gives you 0.250 L. From there, you can use the molar volume of water (18.02 g/mol) and the molar mass of water (18.02 g/mol) to calculate the number of moles using the formula moles = mass/molar mass.
moles KCL = ( M solution ) ( L of solution )moles KCl = ( 0.83 mol KCl / L ) ( 1.7 L ) = 1.41 moles KCl
Molarity is moles of solute per L of solution.moles KCl = ( 1.68 M ) ( 0.121 L ) = ( 1.68 mol/L ) ( 0.121 L )moles KCl = 0.203 moles KCl
moles KCl = ( M solution ) ( V solution in L )moles KCl = ( 2.2 mol KCl / L solution ) ( 0.635 L of solution )moles KCl = 1.397 moles KCl
The answer is 14,93 moles.

To find the total moles of KNO3 needed, use the formula: moles = molarity x volume (in liters). So, moles = 2.0 mol/L x 1.5 L = 3.0 moles of KNO3. Therefore, 3.0 moles of KNO3 need to be dissolved in water to make 1.5 liters of a 2.0 M solution.
