Question

Calculate the molar mass of H2SO4 + 2 NaOH = Na2SO4 + 2 H2O. Please show all work. THANK YOU!

Answer 1

H_2SO_4

`\\ \sf\longmapsto 2(4u)+32u+4(16u)`

`\\ \sf\longmapsto 8u+32u+64u`

`\\ \sf\longmapsto 104u`

`\\ \sf\longmapsto 104g/mol`

NaOH

`\\ \sf\longmapsto 23u+16u+1u`

`\\ \sf\longmapsto 40u`

`\\ \sf\longmapsto 40g/mol`

Na2SO4

`\\ \sf\longmapsto 2(23u)+32u+4(16u)`

`\\ \sf\longmapsto 46u+23u+64u`

`\\ \sf\longmapsto 69u+64u`

`\\ \sf\longmapsto 133u`

`\\ \sf\longmapsto 133g/mol`

H_2O

`\\ \sf\longmapsto 2(1u)+16u`

`\\ \sf\longmapsto 18u`

`\\ \sf\longmapsto 18g/mol`
