To find the answer of the moles of NaOH we need to remember that M=moles/L. Since we are given the molarity and the volume we have all the information we need to solve for moles as follows: 68.5 mL=0.0685L moles=M*L=2.10M*0.0685L=0.14385 moles With sig figs this should give u...
the volume of solution 60.0 g NaOH 1 mole NaOH 1 liter soln = 1.2 Liters of soln 40.0 g NaOH 1.25 moles NaOH Molarity Problems (moles / liter of solution) 1) Calculate the molarity, M, of the following solutions: a) 1.5 moles of NaC 2 H 3 O 2 dissolved in 750 ml of solution....
Molarity =(% "by weight" xx "Density" xx 10)/("Molecular weight") =(13 xx 1.02 xx 10)/98 =132.6/98 =1.35 M 13% solution by weight means that 13 g of solute is dissolved in 87 g of solvent. Thus, molality =(("Weight of solute")/("Molecular weig
Calculate the molality of CsCl in a 19 % by mass aqueous solution? What is the molality of a 4.0 M NaOH solution? The density of the solution is 1.04 g / ml. The number of moles of solute present in 1 kg of a solvent is called its A. Molality. B. Molarity. C. Normality. D....
Osmolarity, also known as osmotic concentration is the number of osmoles of solute present in 1 L solution. 1 M NaCl solution produces 1 mole {eq}Na^+ {/eq} and 1 mole {eq}Cl^- {/eq}. Thus 1 M NaCl solution has an osmolarity of 2 Osmole/L...
To find the mole fraction of the solvent in an aqueous solution of NaOH with a molality of 3, we can follow these steps:Step 1: Understand the definition of molality Molality (m) is defined as the number of moles of solute per
Answer to: An aqueous solution contains 5.1% NaCl by mass. Calculate the molality of the solution and calculate the mole fraction of the solution...
Calculate the molality, molarity, and mole fraction of NH_3 in an 12.80 mass % aqueous solution (Density =0.9651 g/ml). What is the mole fraction, X, of solute and the molality, m (or b), for an aqueous solution that i...
which is calculatedusing molesof solute per kilograms ofsolvent. A solution using these units is called a molal solution (e.g., 0.1 m NaOH is a 0.1 molal solution of sodium hydroxide). UppercaseM is molarity, which is moles of solute per liter of solution (not solvent...
