Question

O = CAL REACTIONG interconverting number of atoms and mass of compound Calculate the mass of hydrazine (N_H.) that contains a million (1.00 x 10) hydrogen atoms. Be sure your answer has a unit symbol necessary, and round it to 3 significant digits.

Answer 1

from the moles and the atom conversions the mass of the hydrazine can be calculated as follows

Hydrogen atoms => Million = 1.0x108 atoms N2 H4 = 32.0452 91 met (molar mass) gmoles N 4 molas H Imol ? - - 6.022X1023 atome 10 x 10 atoms a lot 100 = 6.02271843 1.66057 61018 moles 1 ON 1 mol Nelta - 4 mol Hydrogey Imol Natty contains t) HX 1X60022 X 8,40888184 Hydrogene Tones 32.04529raws of NHY - - #088x1064 Hietaus loxio atoms =) 1.0X106 x 32.04452 2.4088 x184 = 1.330338 x167 graves Acher 3 1.33 X10 ttg
