How many grams of solute are present in 365 mL of 0.590 M KBr?
To find the grams of solute, first calculate the moles of KBr in 365 mL of 0.590 M solution. This is done by multiplying the volume (in liters) by the molarity. Then, use the molar mass of KBr to convert moles to grams.
How many grams of KBr are present in 300.0 mL of a 1.25 M solution?
To find the grams of KBr in the solution, first calculate the moles of KBr present by using the molarity formula: moles = Molarity x Volume (L). Then, convert moles of KBr to grams using its molar mass. For KBr, the molar mass is approximately 119 g/mol. Finally, perform the calculation to find the grams present in the solution.
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 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
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.
How many grams of KBr are required to make 750.0 mL of solution that is 0.0552M molar mass of KBr 119.00gmol?
Multiply the molarity (M, which is in mol/L) with the volume (in L) to get the number of moles needed. Then multiply the result with the molar mass. If you look at the units they will cancel to give an answer in grams. (mol/L)*(L)=mol, (mol)*(g/mol)=g So for the numerical answer you get (0.0552 mol/L)*(0.750 L)*(119.00 g/mol)= 4.93 g KBr
The solution of which substance will hold 70 grams of substance for each 100 grams of water at 30 degrees?
The substance that will hold 70 grams for each 100 grams of water at 30 degrees Celsius is sodium chloride, commonly known as table salt. At this temperature and concentration, sodium chloride is fully soluble and forms a saturated solution.
How many moles of k are needed to form 3.3 moles of KBr?

How many employees does kbr have world wide?
KBR employs approximately 37,000 people worldwide.
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 many moles of kbr are present in 25ml of a 1.5 M solution?
To find the number of moles of KBr in the solution, first calculate the number of moles of KBr in the 25 mL solution using the given concentration and volume. $$moles = concentration \times volume$$ Then, multiply the moles by the molecular weight of KBr to get the mass of KBr in the solution if needed.
