Question

A mass of the crucible (g) 88.000g

Answer 1

A)5.000g
b)mole=mass/molarmass
             molar mass of H2O=18g
             mass of water=5g
b)mole of water=5.000/18.000=0.2778g
c)mass of salt=2.342g
d)mole of salt=mass/molar mass
                     pure salt is NaCl
                     molar mass of NaCl=58.50g
 d)mole of salt=2.342/58.5=0.040mol
e)mole ratio=0.27:0.04
