I hear and read that CO2 (weight:12+16+16=44) causes global warming. The EPA has even designated it as a pollutant. Yet it weighs three times the average molecular weight of air (78% N=14, 21% O=16 and .9% Ar=40). If CO2 is heavier than air, and there is only .038% of our atmosphere, is there...

I was trying to solve this problem, very simply it is: what is the weight of water over lake superior? I did some research and deciced top solve the problem in atmosphere levels But I had no idea of how to use units of volume, mass, and mainly pascals(air preassure) this is what my plan...

The molecular weight of NaCl is 58.44 grams/mole. If you had a 1.0 molar solution (1.0 M) you would have to put 58.44 g of salt in 1.0 liter of solution. How many moles of NaCl would you have in 100 mL of this solution?

Hello every one. I'm finding difficulties to answer this question, can anyone help me to find the correct anwer. Please I really need it soon for my final report lab. The question is, briefly indicate the structural features of minor groove ligands. And another thing I need to write a short intro...
