For 1 mole of water =molecular mass of water (H2O)in grams                                                        =mass of 2H  atoms +mass of O atoms                                                            =2×1+16
=2+16
=18 grams
⇒ for 1 mole

For 0.5 moles = 18×0.5
= 9.0 grams

1 mole of H2O= molecular mass of H20 in grams
=mass of 2Hatoms +mass of O atoms
=2*1+16
=18g
now,1 mole of  H2O=18g
so, mass of 0.5 mole of H2O=18*0.5
=9grams
