Answer:
Option C
Explanation:
Dipole moment being ac vector quantity has both magnitude and direction. All bonding forces have dipole moment ranging from partially positive to negative moment.
Net dipole moment is the dipole moment arising after summation of all the existing dipole moments. On the basis of dipole moment it is determined whether the molecule is polar or non polar.
Hence, option c is correct

We have M1V1=M2V2. Here M1 is to be found, V1=25ml=(25/1000)L &
M2=1.0M, V2=18ml=(18/1000)L.
Therefore M1=(M2V2)V1
so after putting values we get answer 0.72M.
Hope it helps.
Answer:
c. 80 g
Explanation:
metal alloy:
wt% = (mass compound/mass alloy)×100
for antimony:
⇒ 16% = (g antimony / g alloy)×100
⇒ 0.16 = g antimony / g alloy
g alloy = 500 g
⇒ (0.16)×(500 g) = g antimony
⇒ g antimony = 80 g
