What is the molarity of a solution made with 128 grams of magnesium chloride dissolved in one liter of water?
Molarity= moles/Liters To change grams to moles you divide by the mole weight which is listed on the periodic table. Mol= grams/mol weight The Mole weight of Magnesium Chloride is 59.8 grams/mol Mol=128g/59.8 Mol=2.14 Now, you put the number of moles and Liters into the equation Molarity=2.14 mol/1L Molarity=2.14 So, the molarity is 2.14 M
Molarity of CL in 110 ml of a solution containing 5.55g of CaCl2?
To find the molarity of Cl in the solution, first calculate the number of moles of CaCl2 using its molar mass. Then, since each formula unit of CaCl2 contains 2 moles of Cl, multiply the moles of CaCl2 by 2 to get moles of Cl. Finally, divide moles of Cl by the volume of the solution in liters to find the molarity.
What is the molarity of Cl- in 0.220M NaCl?
It is 0.22M also. moles refers to an amount of molecules OR atoms (i.e. ions)
How do you calculate the molarity of the solution of 17.52 grams of Na Cl in a total volume of 2000 ml of solution?
Need moles NaCl first. 17.52 grams NaCl (1 mole NaCl/58.44 grams) = 0.29979 moles NaCl =====================Now. Molarity = moles of solute/Liters of solution ( 2000 ml = 2 Liters ) Molarity = 0.29979 mole NaCl/2 Liters = 0.1499 M NaCl ----------------------
What is the molarity of a 250 ml solution made with 19.55 grams of Na Cl?
To calculate molarity, first find the moles of the solute (NaCl) using its molar mass. The molar mass of NaCl is 58.44 g/mol (Na=22.99 g/mol, Cl=35.45 g/mol). Divide the mass of NaCl (19.55 g) by its molar mass to get moles. Then, divide the moles by the volume of solution in liters (0.25 L) to find the molarity.
How many grammes are there in a cl jar?
A centiliter (cl) is equivalent to 10 milliliters (ml), and the weight in grams of a substance in a cl jar depends on its density. For water, 1 cl is approximately 10 grams. Therefore, the number of grams in a cl jar will vary based on the density of the substance stored in it.
How many grams of solid AgCl are needed to make 4.0 liters of a 5.0 M solution of AgCl?
To determine the mass of AgCl needed, first calculate the number of moles needed using the molarity equation: moles = molarity x volume (in L). Then, convert moles of AgCl to grams by using the molar mass of AgCl (107.87 g/mol for Ag and 35.45 g/mol for Cl). Finally, perform the calculation to find the grams of AgCl required.
What is 15 cl in grams?
15cL equals 0.15L* There are 100cL per liter
What is the volume of 10 micro-liters of 1 Molarity Na-Cl in 1.0 milliliters of water?
1.0 mL of water
How many grams is 64 moles of Cl?
To find the mass of 64 moles of Cl (chlorine), you need to multiply the number of moles by the molar mass of Cl. The molar mass of Cl is approximately 35.45 g/mol. Therefore, 64 moles of Cl would be approximately 2267.2 grams (64 moles x 35.45 g/mol).
How many grams of chlorine can you combine with thirty nine grams of potassium?
Balanced equation. 2K + Cl2 >> 2KCl 39 grams K (1mol K/39.10g )(1mol Cl/2mol K )(35.45g/1 mol Cl ) = 17.7 grams
The sterile solution used to rinse contact lenses can be made by dissolving 400 mg of NaCl in sterile water and diluting to 100 mL. what is the molarity of this solution?
To calculate the molarity of the solution, we first need to determine the number of moles of NaCl in 400 mg. The molar mass of NaCl is approximately 58.44 g/mol. Converting 400 mg to grams gives us 0.4 g. Dividing this by the molar mass gives us approximately 0.0068 moles of NaCl. Since the volume is 100 mL or 0.1 L, the molarity is calculated as moles divided by liters, giving us approximately 0.068 M.
