Calculation of the relative molecular mass, RMM for K2Cr2O7
RMM bagi K2Cr2O7 = 2(RAM for K) + 2(RAM for Cr) + 7(RAM for O) = 2(39) + 2(52) + 7(16) = 294
Calculation of the relative molecular mass, RMM for Fe(NO3)3
RMM for Fe(NO3)3 = RAM for Fe + 3[RAM for N + 3(RAM for O)] = 56 + 3[14 + 3(16) = 242
Calculation of the relative molecular mass, RMM for CCl4
RMM for CCl4 = RAM for C + 4(RAM for Cl) = 12 + 4(35.5) = 154
Calculation of the relative molecular mass, RMM for CH3COOH
RMM 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
Calculation of the relative molecular mass, RMM for Br2
RMM for Br2 = 2(RAM for Br) = 2(80) = 160
Calculation of the relative molecular mass, RMM for CH4
RMM for CH4 = RAM for C + 4(RAM for H) = 12 + 4(1) = 16
Calculation of the relative molecular mass, RMM for C3H8
RMM for C3H8 = 3(RAM for C) + 8(RAM for H) = 3(12) + 8(1) = 44
Calculation of the relative molecular mass, RMM for C2H5OH
RMM for C2H5OH = 2(RAM for C) + 5(RAM for H) + RAM bagi O + RAM bagi H = 2(12) + 5(1) + 16 + 1 = 46
Calculation of the relative molecular mass, RMM for C6H1206
RMM for C6H1206 = 6(RAM for C) + 12(RAM for H) + 6(RAM for O) = 6(12) + 12(1) + 6(16) = 180
Calculation of the relative molecular mass, RMM for Ca(OH)2
RMM for Ca(OH)2 = RAM for Ca + 2(RAM for O) + 2(RAM for H) = 40 + 2(16) + 2(1) = 74
