How many moles are in 550 grams of KCl?
To calculate the number of moles in 550 grams of KCl, first find the molar mass of KCl. Potassium (K) has a molar mass of 39.10 g/mol and chlorine (Cl) has a molar mass of 35.45 g/mol. Add these together to get the molar mass of KCl, which is 74.55 g/mol. Divide the given mass (550 grams) by the molar mass (74.55 g/mol) to find the number of moles. In this case, there are approximately 7.39 moles of KCl in 550 grams.
How many grams are in 3.75 moles of kcl?
To find the number of grams in 3.75 moles of KCl, you would first calculate the molar mass of KCl, which is approximately 74.55 g/mol. Then, you would multiply this molar mass by the number of moles (3.75 moles) to get the answer, which is 279.56 grams of KCl.
How many grams of KCl is needed to make 2 molar solution in 1 liter of water?
To prepare a 2 M solution of KCl in 1 liter of water, you would need to dissolve 149.5 grams of KCl. This is because the molar mass of KCl is approximately 74.5 g/mol, and 2 moles of KCl are needed to prepare a 2 M solution in 1 liter of water.
Calculate the mass in grams of 2.60 mol of potassium chloride (KCl).?
You can calculate the molar mass of potassium chloride (KCl) by adding the atomic masses of potassium (K = 39.10 g/mol) and chlorine (Cl = 35.45 g/mol). The molar mass of KCl is 74.55 g/mol. To find the mass of 2.60 mol of KCl, multiply the molar mass by the number of moles: 2.60 mol * 74.55 g/mol = 193.53 grams.
Which has the higher limiting molar conductivity-NaCl or KCl And what is the reason?
KCl has a higher limiting molar conductivity than NaCl because potassium ions are larger and less hydrated than sodium ions, allowing them to conduct electricity more effectively in solution.
Why the specific molar conductivity of 0.01 M KOH is much higher than the specific conducivity of 0.01M KCl?
This is true because KOH has a high concentration of hydrogen ions (H+) and this increases the conductivity of KOH to be significantly higher than that of KCl. KCl has a very highly electronegative ion Cl- Hydrogen bonding occurs at sites of electronegativity which will interfere conductivity at lower concentrations of these Ions
