¿la masa molecular de anhidrido de lodico 1205 es ?​

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

12 is it do you think so
