How many grams of chromium are there in 85 grams of c2 s3?

Answer. Upon Calculation, you will find that in 80g of Cr2S3 [Chromium(III) sulfide], there is 41.6g of Cr.

How many moles can be produced?

For any balanced chemical reaction, whole numbers (coefficients) are used to show the quantities (generally in moles ) of both the reactants and products. For example, when oxygen and hydrogen react to produce water, one mole of oxygen reacts with two moles of hydrogen to produce two moles of water.

How many molecules are in a mole?

Chemists generally use the mole as the unit for the number of atoms or molecules of a material. One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro’s number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole).

How many moles are in 88g of CO2?

The mass number of CO2 = 2×16 + 12 =44 so one mole of C02 has a mass of 44g. Two moles of CO2 weighs 2 x 44 = 88g.

How many atoms are in CR?

Explanation: The molar mass of elemental chromium is 52.00⋅g⋅mol−1 . What does this mean? It means that if there are 52.00⋅g of chromium metal, there are Avogadro’s number of chromium atoms, i.e. NA chromium atoms, or 6.022×1023 individual atoms.
