Please answer ASAP i will give brainlilest

i don't know, but does anyone wanna be friends? i'm doing my homework at 1: 49 in the morning : /

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?

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.

to this one it would be receptive field
