20/10/2012· Re: What is the concentration of chromate?? You need to pay attention to units and to numbers. According to your first post question says that molar absorbtivity is 5.25x103M-1cm-1 which I guess means 5.25x10 3 M-1 cm-1. Yet you calculate concentration using value of 5.25 no wonder your result is thousand times off.
7/02/2008· You have two 420.0 mL aqueous solutions. Solution A is a solution of silver nitrate, and solution B is a solution of potassium chromate. The masses of the solutes in each of the solutions are the same. When the solutions are added together, a blood-red precipitate forms. After the reaction has gone to completion, you dry the solid and find that it has a mass of 331.8 g.
The mass and molarity of chemical compounds can be calculated based on the molar mass of the compound. The mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass. E.g. Molar mass of NaCl is 58.443, how many grams is 5 mole NaCl? grams = 58.443 × 5 = 292.215 (g)

26/07/2016· Write the chemical formula for potassium phosphate. Look at a periodic table and find the atomic mass for of each element in the formula (potassium, phosphorous, oxygen). Multiply the number of mols of each by its individual mass (i.e., # mols of
It has a molar mass of 332 g/mol. Despite this high molar mass, it has a low enthalpy of 712 kJ/mol due to the ionic bond between silver and chromate. Ionic bonds are weaker than covalent bonds.
Potassium chromate is the inorganic compound with the formula (K 2 CrO 4).This yellow solid is the potassium salt of the chromate anion. It is a common laboratory chemical, whereas sodium chromate is important industrially. It is a class two carcinogen as it contains hexavalent chromium.
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article. Give us

Finding the mass of potassium chromate in a solution from volume and molarity By angelbaby on Thu, 07/24/2008 14:01 What is the mass of potassium chromate, K2CrO4 in 20.0 mL of 6.0 M
30/07/2012· Potassium dichromate has a molar mass of 294 g/mol. To make 100mL of 0.002 mol/L, we need to know how many mol of potassium dichromate are they.. Mol of potassium dichromate = 0.1L(from 100mL) * 0.002 mol/L = 0.0002 mol of potassium dichromate. We know that 1 mol of potash dichrom = 294 g. So 0.0002 mol of potash dichrom = 0.0002 * 294 = 0.0588
19/08/2019· Find the molar mass of the solute. To calculate the number of moles from the mass or grams of solute used, you must first determine the molar mass of the solute. This can be done by adding together the separate molar masses of each element found in the solution. Find the molar mass of each element using the periodic table of elements.
The formula mass divided by total charge of cations 39x2+52+16x4=194/2=97 is the equivalent weight of potassium chromate.

6/01/2015· Here's how you'd go about doing this: You know that molarity is defined as the number of moles of solute divided by the total volume of the solution. Let's try and do this intuitively first. If you want to make 1 L of 0.085 M potassium dichromate solution, you need to add 0.085 moles of K_2Cr_2O_7 to enough water to make 1 L of solution. This will give you C= n/V = ("0.085 moles")/("1 L") = 0
