Web12.0 g carbon is about 1 mole of carbon; 2.0 g of H is about 2 moles and 16.0 g O is about one mole. The molecular weight of this molecule is 30 g/mole, so you divide 60/30 to find how many times you must multiple your empirical formula. The answer is 2 times the above empirical formula, so the molecular formula is C2H4O2 Web22.99 g mol¯1÷ 6.022 x 1023atoms mol¯1= 3.82 x 10¯23g/atom 2) Determine atoms in 1 cm3: 0.968 g / 3.82 x 10¯23g/atom = 2.54 x 1022atoms in 1 cm3 3) Determine volume of the unit cell: (4.29 x 10¯8cm)3= 7.89 x 10¯23cm3 4) Determine number of unit cells in 1 cm3: 1 cm3/ 7.89 x 10¯23cm3= 1.27 x 1022unit cells 5) Determine atoms per unit cell: WebOct 26, 2014 · In order to solve this problem, you need to determine the molar mass of copper, which is the mass of one mole of copper.
