Part 1: a sample of silver (ag) has a mass of 31.78 g. a.) what is the molar mass of silver? b.) how many moles of silver are in this particular 31.78 g sample? c.) how many atoms of silver are in this same sample?show work! you!

I couldn't add it to my page, but this probably works just as well. Hope I didn't do to bad on it for both our sake. Good luck!

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.

the answer is c.the valence of the atoms combine .
