How many moles are in 1.2 kilograms of calcium bromide?
1.2 Kilograms Calcium bromide (1000 grams/1 kilogram)(1 mole CaBr2/199.88 grams) = 6.0 moles calcium bromide
How many moles are in 7.4 kilogram of calcium bromide?
That is a lot of calcium bromide we are dealing with. The formula mass of calcium bromide, CaBr2 is 40.1 + 2(79.9) = 199.9.Amount of CaBr2 = (7.4 x 1000)/199.9 = 32.0mol There are 32 moles of calcium bromide in a 7.4kg pure sample.
How many moles of kbr are present in 25ml of a 1.5 M solution?
Molarity = moles of solute/Liters of solution ( 25 ml = 0.025 Liters ) 1.5 M KBr = moles KBr/0.025 Liters = 0.038 moles potassium bromide ------------------
How many moles of bromine atoms in 1 mole of bromine gas Chemistry question need help with homework?
one mole of a substance is described as 6.02x1023 atoms of a substance so if one mole of bromide gas contains 6.02x1023 atoms then bromide gas will contain one mole. your question is a trick question as the gas is stated as containg one mole there fore it contains one mole of bromide atoms
What is the common therapeutic use of bromide?
Bromide compounds, especially potassium bromide, were frequently used as sedatives in the 19th and early 20th century. Their use in over-the-counter sedatives and headache remedies (such as Bromo-Seltzer) in the United States extended to 1975, when bromides were withdrawn as ingredients, due to chronic toxicity.This use gave the word "bromide" its colloquial connotation of a boring cliché, a bit of conventional wisdom overused as a calming phrase, or verbal sedative.The bromide ion is antiepileptic, and bromide salts are still used as such, particularly in veterinary medicine. Bromide ion is excreted by the kidneys. The half-life of bromide in the human body (12 days) is long compared with many pharmaceuticals, making dosing difficult to adjust (a new dose may require several months to reach equilibrium). Bromide ion concentrations in the cerebrospinal fluid are about 30% of those in blood, and are strongly influenced by the body's chloride intake and metabolism.Since bromide is still used in veterinary medicine (particularly to treat seizures in dogs) in the United States, veterinary diagnostic labs can routinely measure blood bromide levels. However, this is not a conventional test in human medicine in the U.S., since there are no FDA-approved uses for bromide, and (as noted) it is no longer available in over-the-counter sedatives. Therapeutic bromide levels are measured in European countries like Germany, where bromide is still used therapeutically in human epilepsy.
How many atoms are there in 13 moles of bromide?
If you think to a simple binary bromide as NaBr: 166,57.10e23 atoms.
How many moles are in 1.2 kilograms of calcium bromide?
1.2 Kilograms Calcium bromide (1000 grams/1 kilogram)(1 mole CaBr2/199.88 grams) = 6.0 moles calcium bromide
How many moles of ammonium bromide can be produced from 250 moles of bromine and 600 moles of ammonia?
Ther answer is none! ammonium bromide is made from hydrogen bromide and ammonia NH3 + HBr = NH4Br i mole of each makes 1mole of ammonium salt.
How many moles are in 1200 grams of calcium bromide?
The molecular weight of Calcium Bromide is extremely close to 200. So 1200/200 = 6 moles present.
How many moles are in 7.4 kilogram of calcium bromide?
That is a lot of calcium bromide we are dealing with. The formula mass of calcium bromide, CaBr2 is 40.1 + 2(79.9) = 199.9.Amount of CaBr2 = (7.4 x 1000)/199.9 = 32.0mol There are 32 moles of calcium bromide in a 7.4kg pure sample.
Iron bromide FeBr2 contains how many iron atoms?
1
How many moles of bromide ions are present in 750.0 mL of 1.35 M MgBr2?
2.03mol
How many moles are contained in 245g of potassium bromide?
Potassium bromide is KBr, the atomic mass of this compound is ca. 119.1. no.moles = mass/relitive molecular mass, so in this case that's 245/119.1 = 2.057 moles of KBr.
How many atoms in the compound NH4Br?
Ammonium bromide - NH4Br - contain 6 atoms.
How many atoms are found in 10 moles of LiBr?
10 moles LiBr (6.022 X 1023/1 mole LiBr)= 6.022 X 1024 atoms of lithium bromide=========================
How many moles of potassium bromide can be produced from the reaction of 2.92 moles of potassium with 1.78 moles of bromine gas?
First write a balanced chemical equation: 2K + Br2 ---> 2KBR Find the limiting reactant by using the moles of each element and determining which one gives you the smallest number of moles of potassium bromide. 2.92 mol K (2 mol KBr/2 mol K)= 2.92 mol KBr 1.78 mol Br2 (2 mol KBR/1 mol Br2)=3.56 mol KBr potassium is your limiting reactant so the max. number of moles of KBr that can be produced is 2.92 mol of KBr
How many molecules does magnesium bromide have?
Magnesium bromide IS a molecule, or more correctly, it is a formula unit. So, magnesium bromide doesn't HAVE any molecules. One formula unit of magnesium bromide has THREE ATOMS, and they are 1 magnesium atom and 2 bromine atoms (MgBr2).
