Объяснение:

М(CsHSO4) = 133 + 1 + 32 + 16 * 4 = 230  г/моль

w(Cs) = Ar(Cs) *n / Mr(CsHSO)  * 100% = 133/230 * 100% = 57,8%

w(Н) = Ar(Н) *n / Mr(CsHSO)  * 100% = 1/230 * 100% = 0,4%

w(S) = Ar(S) *n / Mr(CsHSO)  * 100% = 32/230 * 100% = 13,9%

w(O) = Ar(O) *n / Mr(CsHSO)  * 100% = 16 * 4/230 * 100% = 27,9%
