Question

83.0 g Lithium Cyanide (LiCN)

Can someone please convert this to molar mass and moles for 100point?
it's not a scam like I really need this done before class is done

Answer 1

Molar mass:-

`\\ \sf\longmapsto LiCN`

`\\ \sf\longmapsto 7u+12u+14u`

`\\ \sf\longmapsto 21u+12u`

`\\ \sf\longmapsto 33u`

`\\ \sf\longmapsto 33g/mol`

• Given mass=83g

No of moles=Given Mass/Molar mass

`\\ \sf\longmapsto (83)/(33)`

`\\ \sf\longmapsto 2.5mol`
