If a large marshmallow has a volume of 2.50 in3 i n 3 and density of 0.242 g/cm3 g / c m 3 , how much would it weigh in grams? 1 in3=16.39 cm3 1 i n 3 = 16.39 c m 3 .

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.

i just learnt this recently but i need to look through my notes again

the answer would be b i believe
