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
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.
What is the symbol for the chromium(II) ion?
Cr^+2 is the symbol for the Chromium(II) ion
How many moles of Cr are there in a sample of Cr that contains 4.37E 23 atoms?
A "mole" of chromium is generally regarded as consisting of Avogadro's Number of atoms. Therefore, 4.37 X 1023 atoms constitutes (4.37 X 1023)/(6.022 X 1023) or 0.726 moles.
What does Cr stand for on the periodic table?
Chromium Chromium Chromium
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 =========================
