hi,

its easy..follow de steps

Nitric acid HNO3
H = 1.
N = 14.
O3 = 16

HNO3 = (1x1) + (14x1) + (16x 3)

= 1+ 14+ 48

=63 g/mol

HNO3 = 63.g/mol

thumbs upp lspls

NONSENSE.......

Suril Dave answered this

molar mass of HNO₃=1+14+16*3

1+14+48=63

MOLAR MASS OF HNO₃=63U

Shwetha Boobalan answered this

who is nonsense..ur only nonsense..taliking rubbish...my answer is laso correct only...mads are not allowed in meritnation..pls go out frm this site

Suril Dave answered this

here molecular mass of HNO₃=63u

molar mass of HNO₃=63g

Suril Dave answered this

hey plz understand this is the right ans we have been made to do like this.............. why don'

you reapect ans and just give thmbz down without seeing........

Suril Dave answered this

thu unit is gram ok...........

Noddy answered this

Nitric Acid= HNO₃

where,, Atomic mass Given as..

H- 1

N= 14

O=16

The molar mass of HNO3= (1)+(14)+(16*3)

= 1 + 14+ 48

= 63g..ans..

Manas Jyoti Das answered this

MOLAR MASS OF HNO3 =(1*1)+(1*14)+(3*16)

THIS MEANS,HIDROGEN ATOM -1

NITROGEN ATOM-1

and OXYGEN ATOM-3

THEREFORE MOLAR MASS- 63 u or 63 gram..................

lol anjali and sindubhatia, stop acting like immature pricks with no life. Hold ur verbal posedown somewhere else but here. i mean come on, u guyz are in 9th grade. u should be mature as well.

u guyz are a disgrace to ur families. take my comment as an advice and don't do this ever again....

PEACE BROTHERS :)

Siva Lalith answered this

H - 1x1=1

N - 1X14=14

O - 3X16=48

total mass of = 1+14+48=63.

what is the mass of 1 mole of nitrogen atoms

Shivansh Bhatnagar answered this

Molar mass of nitric acid HNO3:-
Mass of hydrogen is 1 and there is one hydrogen in HNO3,so here the mass of hydrogen is 1×1=1.
Mass of nitrogen is 14 and there is only one nitrogen in HNO3,so here the mass of nitrogen is 1×14=14.
Mass of oxygen is 16 and there are 3 oxygen molecules in HNO3,so the mass of oxygen is 3×16=48.

Now,the molar mass of HNO3 is the sum of masses of hydrogen,oxygen and nitrogen.
i.e.,1+14+48==63.
