How many total moles of KNO3 must be dissolved in water to make 1.5 liters of a 2.0 M current?
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.
How many moles of KCI would be dissolved in 4 L of water to make 2 M solution?
To make a 2 M solution of KCl in 4 L of water, you would need 8 moles of KCl. This is because Molarity (M) is defined as moles of solute divided by liters of solution. In this case, 2 M means 2 moles of KCl per liter, which totals 8 moles for 4 liters.
How many moles of sodium chloride are in 5.08 L of a 2.36 M solution?
To find the number of moles of sodium chloride, you can multiply the volume of the solution by its molarity. moles = volume (L) * molarity moles = 5.08 L * 2.36 mol/L moles = 11.9928 mol Therefore, there are approximately 11.99 moles of sodium chloride in 5.08 L of a 2.36 M solution.
How many moles NaOH would be in 450 mL of 0.25 N NaOH?
First, calculate the number of moles of NaOH: Moles = Molarity x Volume (L) Convert mL to L: 450 mL = 0.45 L Moles = 0.25 N x 0.45 L = 0.1125 moles of NaOH.
How many moles of HCl are found in 50 mL of a 6.0 M solution?
To find the number of moles, first calculate the number of moles of HCl in the 50 mL solution by multiplying the volume (in liters) by the molarity. Volume in liters = 50 mL / 1000 mL/L = 0.05 L Moles = 0.05 L * 6.0 mol/L = 0.3 moles of HCl.
How many number of moles in 1 litre water?
1 liter of (liquid) water contains 55.5 moles.
How many moles are in 4.54 L of CO?
4,54 L of CO have 0,182 moles.
How many moles of HCl are in 3.36 mL of 22.22 M HCl and 81.5 mL of water?
0.0747mol/L of HCL 1.81mol/L of water
How many moles are in 0.125 L of Ne?
0,125 L neon is equivalent to 0,0056 moles.
How many moles of water are in 250.0 mL of water?
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.
How many moles of KCl are contained in 1.7L of a 0.83M KCl solution?
moles KCL = ( M solution ) ( L of solution )moles KCl = ( 0.83 mol KCl / L ) ( 1.7 L ) = 1.41 moles KCl
How many moles of KCl are contained in 121mL of a 1.68M KCl solution?
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
