Answer:

601 gram

Explanation:

1st we should know how may moles are there in 1.34 X 10 25 atoms

# moles of Al = # of atoms / # of Avogadro's num

= 1.34 X 10 25/ 6.12X10 23 =

= 22.26 mol of AL

so mass of AL = moles x m.wt

=22.26 x 26.98 = 600.55 = 601 gram

Answer:

The equation is balanced

Explanation:

NaCl (aq) + AgNO3(aq) ––> AgCl (s) + NaNO3 (aq)

NaCl (aq) + AgNO3 (aq)

Na = 1 , Cl=1 , Ag = 1 , No3= 1

AgCl (s) + NaNO3 (aq)

Ag = 1 , Cl=1 , Na = 1 , No3= 1
