How many atoms are in 8.25 mole of chromium?
1 mole = 6.022e23 atoms 8.25 mole = 4.96815 e 24 atoms
How many atoms are presents in 3 moles of chromium?
1.8x10*24
How many atoms are in sample of chromium with a mass of 13 grams?
Take the actual sample weight of 13grams, and divide it by the atomic weight of chromium. This gives you your molar percentage of atoms. Now multiply this molar percentage by Avogadro's constant, the number of atoms in one mole, and this will give you your number of atoms in the sample.
Why potassium chromate shows yellow color?
Due to the Chromium(VI) atoms
Is chromium a ion neutral or isotope?
A chromium ion is not neutral. By definition an ion is not neutral. All atoms belong to an isotope, but that has nothing to do with whether the atom is ionized or not.
What is the empirical formula of chromium oxide?
Two Chromium Atoms, and 3 Oxygen Atoms. (Cr2O3)
How many atoms are there in one molecule of Cr(NO3)3?
Chromium(III) nitrate is not made of molecules. It is ionic. There are 4 ions in one formula of chromium(III) nitrate.
How many chromium atoms and how many oxygen atoms are indicated on the right side of this balanced chemical equation 4 Crs 3 O2g 2 Cr2O3g?
2(2+3)=10 atoms 4 chromium atoms and 6 oxygen atoms
How is potassuim dichromate collected?
Due to Chromium(VI) atoms
Is chromium nitrate ionic or molecular?
both. the chromium metal would form an ionic bond, and chromium nitrate is molecular because it contains atoms of different elements.
What is the total number of atoms in Chromate?
Total 5 atoms in chromate (1 of Chromium and 4 of Oxygen)
How many atoms are in 8.25 mole of chromium?
1 mole = 6.022e23 atoms 8.25 mole = 4.96815 e 24 atoms
How many atoms are presents in 3 moles of chromium?
1.8x10*24
How many Cr atoms are in 147.6 kg of chromium?
Quite a few! 147.6 kg chromium (1000 grams/1 kg)(1 mole Cr/52.00 grams)(6.022 X 1023/1 mole Cr) = 1.709 X 1027 atoms of chromium =========================
How many atoms are in sample of chromium with a mass of 13 grams?
Take the actual sample weight of 13grams, and divide it by the atomic weight of chromium. This gives you your molar percentage of atoms. Now multiply this molar percentage by Avogadro's constant, the number of atoms in one mole, and this will give you your number of atoms in the sample.
1.45gm of sample of chromium contains how much atoms?
1.45 g Cr x (1 mol Cr/52.0 g Cr) x (6.022x 1023 atoms Cr/1 mol Cr) = 1.68 x 1022 atoms
Why potassium chromate shows yellow color?
Due to the Chromium(VI) atoms
