Calculate the mass of 3.4 moles of nitric acid (HNO3). Explain the process or show your work by including all values used to determine the answer.

for points guys

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.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

so what is the problem with your lab report and whats the subject of the lab report? i will you
