Question

Please complete this ASAP!!!!!! NEED HELP

Answer 1

1. Moles of 19.6 gram Aluminium

as we know that

Atomic mass of Al = 27 g/mol

`n_(Al) = (19.6)/(27) = 0.725`

2. moles of 15.7 g Nitrogen

as we know that

Atomic mass of nitrogen = 28 g/mol

`n = (15.7)/(28) = 0.56`

3. moles of 15.9 g Water

as we know that

Atomic mass of water = 2 + 16 = 18 g/mol

`n = (15.9)/(18) = 0.88`

4. moles of 10 g Ammonia

as we know that

Atomic mass of Ammonia = 14+ 3 = 17 g/mol

`n = (10)/(17) = 0.588`

5. moles of 14.2 g Ammonium Phosphate

as we know that

Atomic mass of Ammonium Phosphate = 14(3) + 31 + 16(4) = 137 g/mol

`n = (14.2)/(137) = 0.104`
