needed . But herre there is 0 704 mol ,so Na,sOy,
The baknced reachon is
Na, so, + Ba (NO,),
Na, SO4
Ba So, + a NANO,
tor I mole of Na,SO, and Ba No,), , I mole of Basoy
will form as it is char from balanced eachi'on
moles are in 1o0q Na,so,
many
So
have to find how
we

0.191 mol
We know that forr I mole Ba(NO,), I mole Na, soL
o 191 mol of Ba(NO,), is available
buf only
so affer consuming o.191 BaNOg), no more will be left
So only o191 mol of Na, so, will
Alse we know that for I mole Ba (NO), mole ofc
consumed.
Also
,I mole of
BaSOy will form.

That is for
form. But we have to findd it in grams

numbenof moles of Baso,
given
molar mass of BasOy

Roporting it to least number of signihicant
Figure, 45 gof Baso, will form
c) As
Hgure out im
s o 704 mol of Na, sa, and o191 molof
above part
we
there is

BaNg), is available .
So afer reaeling o191 mole
0.191 mole of Na,so,
of Bu(NO)a with
no
more
BalNO,), i available, so reachon will stop
Liming reastant is the reaclant that get consumed
competly in a reachion finst.
So heve limiting
neastant is BaNG),
