How many moles are contained in 22.23 g KBr?
To find the number of moles in 22.23 g of KBr, we need to divide the given mass by the molar mass of KBr. The molar mass of KBr is 119 g/mol. Therefore, 22.23 g of KBr is equal to 0.187 moles.
How do you balance K plus Br2 equals KBr?
To balance the equation K + Br₂ → KBr, you need to make sure the number of atoms of each element is the same on both sides of the equation. To balance this equation, you need to put a coefficient of 2 in front of KBr. This way, you will have 2 potassium atoms, 2 bromine atoms, and 2 KBr molecules on both sides of the equation.
What are the numbers for equation koh hbr equals kbr h2o?
The equation you mentioned is: KOH + HBr → KBr + H2O. This is a neutralization reaction between potassium hydroxide and hydrobromic acid to form potassium bromide and water.

If you have 670.0 grams of water and wish to make a 2.13 m solution of KBr how many grams of the solute would you have to add to the water that you have?
To make a 2.13 M solution of KBr, you need to determine the number of moles of KBr required using the formula Molarity = moles of solute / volume of solution in liters, then calculate the mass of KBr needed using its molar mass. Once you have the mass of KBr, you can add it to the water to prepare the solution.
A 532.1mg sample of impure kBr is treated withAgNo3 and 814.5 mg A gBr is obtaiedwhat is purity of kBr?
To find the purity of KBr, we need to calculate the percentage of KBr in the 814.5 mg of AgBr obtained. Since AgBr has a molar mass of 187.77 g/mol and KBr has a molar mass of 119 g/mol, we can find that the molar ratio of KBr to AgBr is 119/187.77. Then we can calculate the purity as (119/187.77) * (814.5/532.1) * 100%.
How many moles of k are needed to form 3.3 moles of KBr?
357
How can prepare .01N KBr solution?
To prepare a 0.01N KBr solution, dissolve 0.74g of KBr in 1 liter of water. This will give you a solution with a molarity of 0.01N for KBr.
When was KBR - company - created?
KBR - company - was created in 1998.
When was KBR Tower created?
KBR Tower was created in 1973.
How many grams does 3.30 moles of KBr weigh?
There are two steps to solving this problem:Step 1: Calculate the molar mass of KBr (molar mass is the amount, in grams, that one mole of a substance weighs).From the periodic table, we see that the molar mass of K is 39.10 g/mol (its average atomic mass). Similarly, the molar mass of Br is 79.90 g/mol. Adding these numbers together gives the molar mass of KBr, 119 g/mol.Step 2: Calculate the weight, in grams, using the molar mass and the number of moles.For every one mole of KBr, you have 119 grams of KBr:mass (m) = 119 g/mol * 3.30 molmass (m) = 392.7 gTherefore, 3.30 moles of KBr weighs approximately 392.7 grams.
