Web1 mol means there are 6.02 X 10^23 atoms 3 Kunal Agrawal 2 y Okay , So first we will find no of moles of elements in so2 There is 1 s (sulphur atom) and 2 o (oxygen atom) in so2 So in so2 contain 3 atom So 1 mole of so2 will contain 3 mole of atoms. I mole is equal to 6.02214076 x 10^23 So 3 x 6.02214076 x 10^23 will be 18.06642228 x 10^23
WebFirst, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams. how many bytes are there in 3 kbWebAnswer (1 of 2): 1 mol atoms = 6.022 ⨯ 10²³ atoms Moles of Al Calculate the moles (n) of Al in 9.0 g from its mass and molar mass (M).
