How many grams does 500 moles of CuBr weigh?
The molecular weight of CuBr = (63.5 + 79.9) = 143.4 g/mol. 143.4 g/mol * 500 mol = 71700 g CuBr.
How many 500 grams needed to equal 2 kilograms?
1000 gms = 1 kg therefore four 500 gms= 2 kg(kilograms)
500 grams equals how many onces?
There are 17.2 ounces in 500 grams. To get this answer you divide 500 grams by 29 = 17.2. There are 29 grams in one ounce.
How many ounces is 500 grams?
There's 454 grams in a pound and 16 ounces in a pound. So if you divide 454 by 16 you get 28.375 grams per ounce. Divide 500 by 28.375 to get how many ounces in 500 grams... there's 17.62 ounces in 500 grams.
How many moles of CO in 1.23g of it?
For this you need the atomic (molecular) mass of CO. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.4.5 grams / 28.0 grams = .161 moles CO
How many moles in 500 grams of radium?
500 grams of radium is equal to 2,21 moles.
If you have 500 grams of NH3 how many moles to you have Please help and explain how you got the answer?
The molar mass of ammonia is 17,031 g.17,031 g NH3-------------------1 mol500 g NH3-------------------------xx= 500/17,031 = 29,36 moles
How many moles in 5 grams of NaCl?
For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.11.5 grams Na / (23.0 grams) = .500 moles Na
How many grams in 500 calories?
500 grams of what?
What is the molarity of a solution in which 51 grams of aluminum oxide Al2O3 is dissolved in 500 mL of solution?
Need moles aluminum oxide first. 51 grams Al2O3 (1 mole Al2O3/101.96 grams) = 0.5002 moles Al2O3 ======================Now, Molarity = moles of solute/Liters of solution (500 ml = 0.500 Liters ) Molarity =0.5002 moles Al2O3/0.500 Liters = 1.0 M Al2O3 solution ----------------------------
500 millograms equals how many grams?
500 milligrams is equal to .5 grams.
How many grams of NaOH are contained in 500mL of 0.5M NaOH?
First, you must find the amount of moles of NaOH, using the concentration and volume given. By lowercase m, I'm assuming you mean molality, or molals of solution, which is the equation:molality (m) = (moles of solute) / (total volume of solution (in liters))To solve for moles of NaOH, your solute, rearrange the equation by multiplying volume on both sides to get:moles solute = (molality)(total volume of solution)Next, just plug in the information you know, which is 500 mL for the total volume and 125 m for the molality.***Volume for concentration problems must be converted to liters, so remember that 1 L = 1000 mLmoles NaOH = (125 m)(0.500 L) = 62.5 molesFinally, convert this to grams by finding the molar mass of NaOH using the periodic table:22.99 + 16.00 + 1.008 = 39.998 g/mol62.5 moles (39.998 g) / (1 mol) =249.875 grams NaOH
How many grams does 500 moles of CuBr weigh?

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.
