Neurotransmitter levels in the brain can indicate brain health and neurodegenerative diseases like Alzheimer†s . However , the protective blood-brain barrier BBB makes delivering fluorescent sensors that can detect these small molecules to the brain difficult . Now , researchers in  ACS Central Science  demonstrate a way of packaging these sensors for easy

    The correct answer is b) (n(H2)=6.8 mol, m(Fe3O4)=394 g)Calculating n(H2):n(H2)/n(Fe)=4/3n(H2)=n(Fe)*4/3=5,10*4/3=6,8 molCalculating m(Fe3O4):n(Fe3O4)/n(Fe)=1/3n(Fe3O4)=n(Fe)*1/3=5,10*1/3=1,7 molm(Fe3O4)=n(Fe3O4)*M(Fe3O4)=1,7 mol*231,533 g/mol=393,6061 gHope this comment was helpful!
