What is the molarity of a solution that contains 4.53 moles of lithium nitrate in 2.85 liters of solution?
This molarity is 1,59.
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=========================
What is the molarity of a solution that contains 1.1 moles of lithium in 0.5-liters of solution?
Molarity is moles per litre. You need to multiply moles per 0.5 litres by 2. Doing this gives you 2.2 moles per litre, i.e. 2.2 molar.
What is the Molarity of a substance that contains 4.13 grams of magnesium bromide in 845 liters of a solution?
To find the molarity of the substance, divide the moles of the substance by the volume of the solution in liters. First, calculate the moles of magnesium bromide: Convert grams to moles by dividing the given mass by the molar mass of magnesium bromide (184.1 g/mol). Moles of magnesium bromide = 4.13 g / 184.1 g/mol = 0.0224 mol. Next, divide the moles by the volume of the solution in liters: Molarity = 0.0224 mol / 845 L ≈ 0.00003 M (rounded to 3 significant figures).
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 of Lithium chloride need to be added to one liter of total solution to make up a 1.25 M solution?
1.25 moles of Lithium Chloride
How many moles of lithium chloride are dissolved in 3.00L of a 0.200 M solution of lithium chloride?
3 x 0.2 = 0.6 moles
What is the molarity of a solution that contains 31.0 grams of HCl in 500cm3 of solution?
31 grams HCl (1mol/36.458g ) = 0.850 moles 500cm^3 = 0.50 Liters Molarity = moles of solute/liters of solution Molarity = 0.850mol/0.50L = 1.7 Molarity
How many moles of lithium chloride will be formed by the reaction of chlorine with 046 moles of lithium bromide in the following reaction 2 LiBr plus Cl2 equals 2 LiCI plus Br2?
2LiBr(aq) + Cl2(g) = 2LiCl(aq) + Br2(l) will result in .167 moles of lithium chloride.
What is the molarity of a solution that contains 4.53 moles of lithium nitrate in 2.85 liters of solution?
This molarity is 1,59.
What is the molarity of a solution that contains 6.42 moles of lithium nitate in 1.75 liters of solution?
Molarity is moles of solvent divided by liters of solution, so 6.42 / 1.75 = 3.67M.
How many moles of bromide are there in Iron Bromide?
FeBr3 (Iron III Bromide) has three moles of bromide for every mole of iron. FeBr2 (Iron II Bromide) has two moles of bromide ion per mole of Iron.
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 sodium chloride are needed to prepare 500 mL of a 0.250 M solution?
500ml = 500cm3 = 0.5dm3 0.250M = 0.250mol/dm3 number of moles = molarity x volume number of moles = 0.250mol/dm3 x 0.5dm3 = 0.125mol 0.125mol of NaCl is needed to prepare the required solution.
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 ------------------
What is the molarity of a solution that contains 1.1 moles of lithium in 0.5-liters of solution?
Molarity is moles per litre. You need to multiply moles per 0.5 litres by 2. Doing this gives you 2.2 moles per litre, i.e. 2.2 molar.
What volume of 0.256 M sodium bromide contains 18.7 grams of bromide?
Need moles sodium bromide first. 18.7 grams NaBr (1 mole NaBr/102.89 grams) = 0.1817 moles NaBr =====================Now, Molarity = moles of solute/Liters of solution 0.256 M NaBr = 0.1817 moles NaBr/X Liters Liters = 0.1817/0.256 = 0.7098 Liters -------------------------( you do sigi figis )
