Reaction three - First convert vicinal dihalide to alkyne by double dehydrohalogenation using two moles of NaNH2 ---->Deprotonation (Removal of acidic H  from sp carbon) -------> SN2 Nucleophilic substitution reactions CH₃CH₂I

Now you can add them to get total moles

Thankyou ma'am , understood now
