WebExample #2: Calculate the molarity of a dye concentration given the molar mass is of the dye 327 g/mol and a dye concentration of 2 ppm. Solution: 1) Convert ppm to a gram-based concentration: 2 ppm = 2 mg dye / L of solution. 2a) Using 0.002 g/L, caculate the molarity: 0.002 g/L divided by 327 g/mol = 6.1 x 10-6 M Webcadmium (Cd), chemical element, a metal of Group 12 (IIb, or zinc group) of the periodic table. atomic number48 atomic weight112.414 melting point321 °C (610 °F) boiling point765 °C (1,409 °F) specific gravity8.65 at 20 °C … philly arena football

Chromium Molar Mass - BRAINGITH

Web(a) Determine the molar mass of KMnO 4; determine the number of moles of KMnO 4 in the solution; from the number of moles and the volume of solution, determine the molarity; (b) 1.15 \(×\) 10 −3 M Consider this question: What is the molarity of HCl if 35.23 mL of a solution of HCl contain 0.3366 g of HCl? WebTo determine the number of moles in 20.0 grams of Cd (cadmium), we need to use its molar mass. The molar mass of Cd is 112.41 g/mol. We can use this value and the given mass to calculate the number of moles as follows: WebJun 23, 2016 · Avogadro's constant says that 1 mole of any atom contains 6.022 ⋅ 1023 atoms. In this case you have 3.40 ⋅ 1022 atoms: 3.40⋅ 1022 atoms 6.022 ⋅ 1023 atoms mol = 5.65 ⋅ 10−2mol. Step 2. The atomic mass of helium (He) will give you the weight of one mole of this molecule: 1 mol = 4.00 gram: 4.00 g mol ⋅ 5.65 ⋅ 10−2mol = 0.226g. tsai periodontist walnut creek
