If each paper clip is 0.88g : 1100 / 0.88 = 1250
1250 paper clips in the box
Explanation:
acid --> HCN
base --> KCN
now
another base NaOH is added
we know that
base will react with an acid
so
OH- + HCN ---> CN- + H20
we can see that
HCN is used up , so number of moles of HCN will decrease
CN- is being formed , so number of moles of CN- will increase.
