To find the number of moles in 260g of chromium, you need to divide the given mass by the molar mass of chromium. The molar mass of chromium is approximately 51.996 g/mol. Dividing 260g by the molar mass gives you about 5 moles of chromium.
1 mole Cr = 51.9961g Cr
1g Cr x 1mol Cr/51.9961g Cr = 0.02 mole Cr
Chromium's molar mass is 51.996 g/mol , so there are 260/51.996 or approximately 5 moles in 260g of chromium.
There are approximately 3 moles of Cr in 156 g of Cr.
156 g Cr / 52 g / mol = 3 mol
1 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 miles of calcium nitrate would react with 4.55 moles of Chromium (III) sulfate to produce chromium (III) nitrate?
To determine how many miles of calcium nitrate would react with 4.55 moles of Chromium (III) sulfate to produce chromium (III) nitrate, you would first need to write the balanced chemical equation for the reaction between calcium nitrate and chromium (III) sulfate. Then, use the stoichiometry of the reaction to convert moles of Chromium (III) sulfate to moles of calcium nitrate, and finally, convert moles of calcium nitrate to miles using the 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 of H2O are present in 75.0g H2O?
There are 4.17 moles of H2O present in 75.0g of H2O.
How many moles of sulfur are present in 3 moles of aluminum sulfate?
There are 6 moles of sulfur present in 3 moles of aluminum sulfate, because aluminum sulfate has a 2:3 ratio of aluminum to sulfur.
How many moles of hydrogen are need to convert 5 moles of chromium oxide?
The balanced chemical equation for this reaction is: Cr2O3 + 3H2 -> 2Cr + 3H2O. So, according to the equation, 3 moles of hydrogen are needed to convert 1 mole of chromium oxide. Therefore, to convert 5 moles of chromium oxide, 15 moles of hydrogen would be needed.
