∙ 8y agoThere are approximately 3 moles of Cr in 156 g of Cr.
156 g Cr / 52 g / mol = 3 mol

∙ 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?
To calculate the number of grams-moles (gmole) of chromium(II) hydroxide, you need to know the mass of chromium(II) hydroxide in grams and its molar mass. Once you have these values, you can use the formula: gmole = mass (in grams) / molar mass.

How many gmole of chromium II hydroxide?
To calculate the number of grams-moles (gmole) of chromium(II) hydroxide, you need to know the mass of chromium(II) hydroxide in grams and its molar mass. Once you have these values, you can use the formula: gmole = mass (in grams) / molar mass.
How many moles are present in 1.64g of MgSO4?
To calculate the number of moles in 1.64g of MgSO4, you first need to determine the molar mass of MgSO4 which is 120.37 g/mol. Next, divide the given mass by the molar mass to get the number of moles. In this case, 1.64g ÷ 120.37 g/mol ≈ 0.014 moles of MgSO4.
How many moles of sulfur are present in 5 moles of H2So4?
5 moles
How many moles of Mg are present in 14.95 g?
The answer is 0,615 moles.
How many moles of H2O are present in 150.0G of H2O?
The answer is 8,33 moles.
How many moles are in 92g of ethanol?
To find the number of moles in 92g of ethanol, we first need to know the molar mass of ethanol, which is approximately 46g/mol. Then, we divide the given mass by the molar mass to get the number of moles. So, 92g of ethanol is equal to 2 moles.
