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 moles of Cr are there in a sample of Cr that contains 4.37E 23 atoms?
To find the number of moles of Cr in the sample, first calculate the molar mass of Cr (chromium). Chromium has an atomic mass of approximately 51.996 g/mol. Next, divide the number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol) to convert atoms to moles. So, 4.37 x 10^23 atoms of Cr is equivalent to 0.725 moles of chromium.
What is the empirical formula of chromium oxide?
Two Chromium Atoms, and 3 Oxygen Atoms. (Cr2O3)
What is formula for chromium sulfide?
Chromium VI sulphate Cr(SO4)3
1.45gm of sample of chromium contains how much atoms?
To determine the number of atoms in 1.45g of chromium, you need to calculate the number of moles of chromium using its molar mass (51.996 g/mol) and then use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms. By dividing the mass of the sample by the molar mass, you can find the moles present, and then multiply the moles by Avogadro's number to find the number of atoms.
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 found in dichromate?
A dichromate ion (Cr2O7^2-) contains a total of 9 atoms - 2 chromium (Cr) atoms and 7 oxygen (O) atoms.
What are chromium atoms?
Chromium atoms are the smallest unit of the chemical element chromium. Chromium is a transition metal with the atomic number 24 and is commonly used in the manufacturing industry for its corrosion resistance and ability to enhance the hardness of materials.
Which has more atoms 1.1 g of hydrogen atoms or 14.7g of chromium atoms?
For this you need the Atomic Mass of Cr. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.11.9 moles Cr × (52.0 grams) =618.8 grams Cr
