Answer 1

\(PTK\left(SO_2\right)=32\cdot16\cdot2=64\left(amu\right)\\ PTK\left(CO_2\right)=12\cdot16\cdot2=44\left(amu\right)\\ PTK\left(CH_4\right)=12+4=16\left(amu\right)\\ PTK\left(NH_3\right)=14+3=17\left(amu\right)\\ PTK\left(O_2\right)=16\cdot2=32\left(amu\right)\\ PTK\left(N_2\right)=14\cdot2=28\left(amu\right)\\ PTK\left(HCl\right)=1+35,5=36,5\left(amu\right)\\ PTK\left(Cl_2\right)=35,5\cdot2=71\left(amu\right)\\ PTK\left(NaCl\right)=23+35,5=58,8\left(amu\right)\)
