How many grams of NH3 are needed to prepare 800 mL of a 0.20 M NH3 solution? How many grams of Fe(NO_3)_3-9H_2O are required to prepare 400.0 mL of a 0.399 M solution of Fe(NO_3)_3-9H_2O? How many grams of Cu(NO3)2 are required to prepar...
A humidified chamber is perfect for the IF procedure and can easily be self-made (see Slideshow "How to prepare a humidified chamber"). It prevents drying of the preparation and allows incubation in the dark, which is important in handling fluorochromes and necessary for already existing fluore...
How many grams of solute are needed to prepare 1.00 L of 0.195 M NaCl solution? If the molality of a CaCl2 solution is 0.100 mol/kg, and was made from 500.0 mL of water, how many grams of CaCl2 were needed to make the solution? How many grams of solute are in...
Answer to: A solution of CaCl2 is prepared by dissolving 1.004 g of the solid in approximately 30 mL of water. How many moles of CaCl2 does this...
How to Calculate Volume Percent Concentration of a Solution Volume percentis the volume of solute per volume of solution. This unit is used when mixing together volumes of two solutions to prepare a new solution. When you mix solutions, the volumesaren't always additive, so volume percent is ...
Step-by-Step Text Solution:1. Definition of Nessler's Reagent: Nessler's reagent is an alkaline solution of potassium mercury(II) iodide, represented chemically as K2HgI4. It is used primarily for the detect
This secondary container is to prevent the basic solution from accidentally splashing onto your bench top or onto other equipment. Pour your cleaning solution over your slides and shake (gently!) for 2 hours at room temperature. Then rinse your slides well with distilled water. When done, keep...
How much water would I need to add to 500 mL of a 2.4 M KCl solution to make a 1.0 M solution?Calculating the amount of water:The required amount of water during the preparation of a dilute solution is determined after knowing the values of three param...
A chemist needs 130 ml of a 72 \% solution but has only 17 \% and 82 \% solutions available. Find how many ml of each that should be mixed to get the desired solution. How many grams (g) of KCl are needed to prepare ...
