- What is the molarity of a solution composed of - Socratic
342 15 grams is the molar mass of aluminum sulfate You can use this value to convert from moles to grams and from grams to moles, depending on what's given in the problem Now we have everything we need to calculate the molarity, but don't forget to convert mL into L: Molarity = #(0 015 " moles " Al_2(SO_4)_3) (0 125 " L") = 0 12#
- If I have a 247 mL bag at a temperature of 20. 9 degrees C . . . - Socratic
If I have a 247 mL bag at a temperature of 20 9 degrees C, and I leave it in my car which has a temperature of 64 0 degrees C, what will the new volume of the bag be? Chemistry 1 Answer
- A cylindical container 30cm in diameter holds approach . . . - Socratic
V_("cylinder") = A_(base) * h = pi r^2 h r = d 2 = 30 2 = 15 cm V_("cylinder") = pi 15^2 h = 225 pi h " "cm^3 Convert liters to cm^3 1 cm^3 = 1 mL; " " 1 L = 1000 mL 30 L xx (1000 mL) (1 L) xx (1 cm^3) (1 mL) = 30,000" " cm^3 1 L xx (1000 mL) (1 L) xx (1 cm^3) (1 mL) = 1,000" " cm^3 Find the original height (not sure you really need this): V
- If the total volume of the resultant - Socratic
An approach that is something you may have been taught is to assume that the volume is entirely additive (even though it really isn't) Normally, however, that's a pretty good assumption Also, since the total volume AFTER adding the solid was given as "50 0 mL", there is no doubt that that is the true volume If it went unstated when the volume was measured, then that wouldn't be the true
- If 500 mL of HCl gas at 300 K and 100 kPa dissolved in pure . . . - Socratic
The concentration of the NaOH solution is 1 60 mol L Write the balanced chemical equation for the reaction Use the Ideal Gas Law to convert litres of HCl to moles of HCl The central part of the problem is to get the molar ratio between HCl and NaOH This gives you the moles of NaOH Use the volume of the NaOH to convert moles of NaOH to molarity of NaOH Balanced Equation HCl + NaOH →
- Question #983bc - Socratic
Here's how you can do that As you know, the molarity of a solution tells you the number of moles of solute present for every "1 L" of the solution In order to make the calculations easier, pick a sample of this solution that has exactly "1 L" = 10^3 quad "mL" Use the density of the solution to find the mass of the sample In your case, vinegar is said to have a density of "1 005 g mL"^(-1
- If I dissolve a Tums tablet (1000 mg CaCO_3) in 25 mL of . . . - Socratic
This means that the saturated solution of calcium carbonate will contain #3 25 * 10^(-6)# moles of carbonate anions in #"25 mL"# of water, which is essentially equivalent to saying in #"25 mL"# of the solution
- If I have 340 mL of a 0. 5 M NaBr solution, what will the . . . - Socratic
What would be the concentration of a solution made by diluting 45 0 mL of 4 2 M KOH to 250 mL? What is the molarity of a solution that is made by diluting 50 00 mL of a 4 74 M solution of HCl What volume of water would you add to 15 00 mL of a 6 77 M solution of nitric acid in order to
