The calculation of relative formula mass, RFM of N2O4
RFM for N2O4 = 2(RAM for N) + 4(RAM for O) = 2(14) + 4 (16) = 92
The calculation of relative formula mass, RFM of C4H10
RFM for C4H10 = 4(RAM for C) + 10(RAM for H) = 4(12) + 10(1) = 58
The calculation of relative formula mass, RFM of CuCl2
RFM for CuCl2 = RAM for Cu + 2(RAM for Cl) = 64 + 2(35.5) = 135
The calculation of relative formula mass, RFM of Zn(OH)2
RFM bagi Zn(OH)2 = RAM for Zn + 2(RAM for O) + 2(RAM for H) = 65 + 2(16) + 2(1) = 99
The calculation of relative formula mass, RFM of K2Cr2O7
RFM bagi K2Cr2O7 = 2(RAM for K) + 2(RAM for Cr) + 7(RAM for O) = 2(39) + 2(52) + 7(16) = 294
The calculation of relative formula mass, RFM for Fe(NO3)3
RFM for Fe(NO3)3 = RAM for Fe + 3[RAM for N + 3(RAM for O)] = 56 + 3[14 + 3(16) = 242
The calculation of relative formula mass, RFM of CCl4
RfM for CCl4 = RAM for C + 4(RAM for Cl) = 12 + 4(35.5) = 154
The calculation of relative formula mass, RFM of CH3COOH
RfM for CH3COOH = RAM for C + 3(RAM for H) + RAM for C + RAM for O + RAM for H = 12 + 3(1) + 12 + 16 + 16 + 1 = 60
The calculation of relative formula mass, RFM of Br2
RFM for Br2 = 2(RAM for Br) = 2(80) = 160
The calculation of relative formula mass, RFM of CH4
RFM for CH4 = RAM for C + 4(RAM for H) = 12 + 4(1) = 16
