Which elements are in KBr?
The elements in this formulae are Potassium (which is a metal which reacts with water on contact) and bromine ( which is a non-metal that is a liquid at room temperature).
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.
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.
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.
How many grams are in 3 mole of KBr?
Easy...the periodic table gives the average mole weight of each element averaged out over all it's naturally occurring, if any, isotopes, i.e., K is 39.09 Br is 79.9 Add them up and it's (to three significant figures): So KBr is 119 g/mole
What elements make up potassium bromide?
Potassium bromide is composed of two elements: potassium (K) and bromine (Br). Potassium is a metal and bromine is a non-metal. The chemical formula for potassium bromide is KBr.
Which elements are in KBr?
The elements in this formulae are Potassium (which is a metal which reacts with water on contact) and bromine ( which is a non-metal that is a liquid at room temperature).
Is kbr a compound or element?
KBr, or potassium bromide, is a compound. It is formed from the chemical combination of potassium (K), which is an element, and bromine (Br), another element. In KBr, these elements are bonded together in a fixed ratio, resulting in a substance with distinct properties different from those of the individual elements.

Once you have the mass of KBr, you can add it to the water to prepare the solution.
What are the elements name of PBS KBr RaO?
PBS KBr RaO consists of four different elements: phosphorus (P), potassium (K), bromine (Br), and radium (Ra), along with oxygen (O). Each of these elements plays a distinct role in the compound, contributing to its overall properties and characteristics. In this case, "PBS" likely refers to a compound containing phosphorus, while "KBr" indicates potassium bromide, and "RaO" signifies radium oxide.
What elements make up elements of sugar?
Carbon, hydrogen and oxygen are the only elements that make up sugars.
What two compounds equal KBr?
K is Potassium and Br is Bromine. These are both Elements but together they form a compound
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.
