∙ 11y agoChromium's molar mass is 51.996 g/mol , so there are 260/51.996 or approximately 5 moles in 260g of chromium.
Wiki User
∙ 8y agoThere are approximately 3 moles of Cr in 156 g of Cr.
156 g Cr / 52 g / mol = 3 mol
Wiki User
∙ 11y ago1 mole Cr = 51.9961g (atomic weight in grams)
200g Cr x 1mol/51.9961g = 3.85mol Cr = 4mol Cr rounded to 1 significant figure

How many gmole of chromium II hydroxide?
So you have 2 moles of Chromium (Cr). Use equation moles=mass (in grams)/RMM. The bottom can be called Relative Molecular Mass (RMM), or Relative Atomic Mass (RAM) depending on the situation. Chances are you know it as Molar mass. You can call it that too. Using moles= mass (g)/RMM --> 2 moles = mass (g)/51.996 --> 2 x 51.996 = the mass in grams of Chromium --> 103.992g in 2 moles of Chromium.
