The answer is 59,967 grams.
5.2701 ´ 1023 molecules hydrogen peroxide
38 grams oxygen gas (1 mole O2/32 grams)(6.022 X 1023/1 mole O2) = 7.2 X 1023 molecules of oxygen gas -------------------------------------------------
200 grams H2O (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.69 X 1024 molecules of water ======================
divide the amount of particles given in the question by avagado's number to get the amount in moles. 3.01 x 1023 / 6.022 x 1023 which is about 0.5 moles. them multiply the amount of moles by the mass of Nitrogen to get it in grams. 0.5 x 14 = 7g
8 grams NaOH (1 mole NaOH/39.998 grams) = 0.2 moles NaOH
1 mole C4H10 = 58.1222g = 6.022 x 1023 molecules 11.7g C4H10 x 6.022 x 1023 molecules/58.1222g = 1.21 x 1023 molecules C4H10
5.2701 ´ 1023 molecules hydrogen peroxide
38 grams oxygen gas (1 mole O2/32 grams)(6.022 X 1023/1 mole O2) = 7.2 X 1023 molecules of oxygen gas -------------------------------------------------
72 grams SO2 (1 mole SO2/64.07 grams)(6.022 X 1023/1 mole SO2) = 6.8 X 1023 molecules of sulfur dioxide ============================
6,022.1023
How many molecules are in 94 grams of sodium fluoride
1 mole HgO = 216.59g HgO = 6.022 x 1023 molecules HgO 64.0g HgO x (1mol HgO/216.59g HgO) x (6.022 x 1023 molecules HgO/mol HgO) = 1.78 x 1023 molecules HgO
200 grams H2O (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.69 X 1024 molecules of water ======================
Avogadro's number. I will show you. 18.02 grams water (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.021 X 1023 atoms of water ----------------------------------------
1 mole of molecules = 6.022 x 1023 molecules 0.536mol x 6.022 x 1023 molecules/mol = 3.28 x 1023 molecules
1 mole of molecules = 6.022 x 1023 molecules 1.25 moles of molecules x 6.022 x 1023 molecules/mol molecules = 7.53 x 1023 molecules
8 grams NaOH (1 mole NaOH/39.998 grams) = 0.2 moles NaOH
