What volume would be occupied by 16.0 g of CH4 at 00C and 760 mmHg?

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.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

the answer is a for sure mark brainliest i had got this right on usatestprep
