Question

oblicz masy cząsteczkowe
mSo2, mH2So4, mK3Po4, mCuSo4, mNaNO3, mCaSO4, mFe2S3

Answer 1

Jednostką masy cząsteczkowej jest unit.

 

mSO2, to 32u+32u=64u

mH2SO4 to 2u+32u+64u=98u

mK3PO4 to 117u+31u+64u=212u

mCuSO4 to 64u+32u+64u=160u

mNaNO3 to 23u+14u+48u=85u

mCaSO4 to 40u+32u+64u=136u

mFe2S3 to 112u+96u=208u

 

 

Answer 2

mSo2 = 32u + 2 * 16u = 32u + 32u = 64u

mH2So4 = 2 * 1u + 32u + 4 * 16u = 2u + 32u + 64u = 98u

mK3Po4 = 3 * 39u + 31u + 4 * 16u = 117u + 31u + 64u = 213u

mCuSo4 = 64u + 32u + 4 * 16u = 64u + 32u + 64u = 160u

mNaNO3 = 23u + 14u + 3 * 16u = 23u + 14u + 48u = 85u

mCaSO4 = 40u + 32u + 4 * 16u = 40u + 32u + 64u = 136u

mFe2S3 = 2 * 56u + 3 * 32u = 112u + 96u = 208u

u = unit
