Thirty Grams Of Lye Was Dissolved In Enough Water To Make 1l Of Solution How Many Grams Of Lye Would Be In 75ml Of The Solution?

Thirty grams of lye was dissolved in enough water to make 1L of solution how many grams of lye would be in 75ml of the solution?

  Scribes the concentration of a solution in moles of solute divided by liters of solution. Masses of solute must first be converted to moles using the molar mass of the solute. This is the most widely used unit for concentration when preparing solutions in chemistry and biology. The units of molarity, mol/L, are usually represented by a scripted capital "M". Calculate the concentration, in moles of solute per liter of solution, of each of the following: Example: 10 grams of NaOH is dissolved in enough water to make 2 L of solution Step #1 - Convert grams of solute to moles of solute: 10 g NaOH 1mol NaOH = 0.250 mol NaOH 40 g NaOH Step #2 – Divide moles of solute by liters of solution: 0.250 mol NaOH = 0.125 M NaOH 2L 1) 20 grams of NaOH is dissolved in enough water to make 1 liter of solution 2) 45 grams of glucose, C6H12O6 is dissolved in enough water to make 0.500 liters of solution 3) 116 grams of KF is dissolved in enough water to make 4 L of solution 4) 63 grams of HNO3 is dissolved in enough water to make 100 liters of solution 5) 280 grams of CaO is dissolved in enough water to make 10 L of solution Percent composition is the ratio of one part of solute to one hundred parts of solution and is expressed as a percent. Determine the mass of solute and solution and then divide the mass of the solute by the total mass of the solution. This number is then multiplied by 100 and expressed as a percent. In dilute water solutions, we can assume that 1 mL of water-based solution has a mass of 1 gram, so 1 liter of solution has a mass of 1000 grams. Example: 10 grams of NaOH is dissolved in enough water to make 2 L of solution 10 g NaOH x100 = 0.5 % NaOH 2000 g solution 6) 20 grams of NaOH is dissolved in enough water to make 1 liter of solution 7) 45 grams of glucose, C6H12O6 is dissolved in enough water to make 0.500 liters of solution 8) 116 grams of KF is dissolved in enough water to make 4 L of solution 9) 63 grams of HNO3 is dissolved in enough water to make 100 liters of solution 10) 280 grams of CaO is dissolved in enough water to make 10 L of solution
