Answer:
[tex]MM_{C_5S_2}=132.19g/mol[/tex]
Explanation:
Hello!
In this case, since the computation of the molar mass requires the molecular formula, we first realize that of pentacarbon disulfide is C₅S₂ due to the given prefixes. In such a way, we multiply the atomic mass of carbon by five and that of sulfur by two as shown below:
[tex]MM_{C_5S_2}=5m_C+2m_S[/tex]
Thus, we plug in the atomic masses given in the periodic table to obtain:
[tex]MM_{C_5S_2}=5*12.01+2*32.07\\\\MM_{C_5S_2}=132.19g/mol[/tex]
Best regards!
