∙ 11y ago
The gram formula mass of CaCl2 is 110.99. By definition, each liter of 0.700 M CaCl2 contains 0.700 gram formula masses of the solute. Therefore, 2.00 liters of such solution contain 1.400 formula masses of the solute, or 155 grams, to the justified number of significant digits.

What is the mass of sodium hudroxide needed to prepare 100 mL of a 0.10 M solution?
1.17 grams :)
7.5 grams of CaCl2 is how many moles?
For this you need the atomic (molecular) mass of CaCl2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. CaCl2=111.1 grams7.5 grams CaCl2 / (111.1 grams) = .0675 moles CaCl2
How many grams of sodium chloride are needed to prepare 600 ml of a 0.9 percent saline solution?
600 mL of 0,9 % sodium chloride: 6 x 0,9 = 5,4 grams NaCl
How many grams of KCl are required to prepare 2.25L of a 0.75m KCl solution?
