Hello!
261.35 g ------------------- 6.02x10²³ formula units
? g -------------------------- 5.30 x10²² formula units
( 5.30x10²² ) x 261.35 / 6.02x10²³
= 1.385x10²⁵ / 6.02x10²³
= 23.0 g
I hope this helps! Have a bless day!
The following are neutral salts: NANO3, BaBr2 AND Ba[OH]2.
Neutral salts are those salts that are formed when a strong base react with a strong acid. In those neutralization reactions, the base completely neutralize the acid to form a neutral salts.
The answer is 2.0, and it is because
M(NaCl)=50.0 g
m(H₂O)=150.0 g
m(solution)=m(NaCl)+m(H₂O)
w(NaCl)=100m(NaCl)/m(solution)=100m(NaCl)/{m(NaCl)+m(H₂O)}
w(NaCl)=100*50.0/(50.0+150.0)=25%
