Step 4: compute the ph of the solutions
for the acids, use the formula ph = -log[h+). (because hci has 1 h+ ion per formula unit, [h] equals the
molarity.) for water, use what you know about the ph of neutral solutions. for the bases, examine and
extend the pattern. done

littering streams           is the answer

and i oop

explanation:

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
