9 moles ntawm H2S = 9 ( 6.022 * 10²³ molecules) = 5.4198 * 10²4 molecules. teb: muaj 5.4198 * 10²4 molecules hauv 9.00 moles ntawm H2S.
Ib yam li ntawd, nws nug, pes tsawg moles nyob hauv h2s?
1 moles
Ib sab saum toj no, pes tsawg molecules nyob hauv 23.0 moles ntawm oxygen? Teb thiab piav qhia: Tus naj npawb ntawm molecules ntawm oxygen hauv 23 moles ntawm oxygen yog 1.385x1025 molecules ntawm oxygen.
Ua li no, pes tsawg molecules nyob rau hauv moles?
Ib mole (cov ntawv luv mol) yog sib npaug rau 6.022 × 1023 molecular Cov koom haum (Avogadro tus naj npawb), thiab txhua lub caij muaj qhov sib txawv molar loj nyob ntawm qhov hnyav ntawm 6.022 × 1023 ntawm nws atoms (1 mole ).
Muaj pes tsawg molecules nyob rau hauv 1.5 moles?
Teb thiab piav qhia: Yog ib qho mole NaCl yuav muaj 6.022 × 1023 6.022 × 10 23 molecules , ces 1.5 hmo yuav muaj: 1.5 ×6.022×1023=9.03×1023 1.5 × 6.022 × 10 23 = 9.03 × 10 23 molecules.
