Two moles because one moles would be 6.02×10 23 atoms 2 moles would equal twice that number of atoms
Maybe like a diamond or something
<span>Molality(m) or molal concentration is a measure
of concentration and it refers to amount of substance in a specified amount of
mass of the solvent. Used unit for molality is mol/kg which is also
sometimes denoted as 1 molal. It is equal to the moles of solute (the substance
being dissolved) divided by the kilograms of solvent (the substance used to
dissolve).</span>
Molarity(M) or molar concentration is also a
measure of concentration and represents the amount of substance per unit volume
of solution(number of moles per litre of solution. Used unit for molarity is
mol/L or M. A solution with a concentration of 1 mol/L is equivalent to 1 molar
(1 M).
Molality is preferred when
the temperature of the solution varies, because it does not depend on
temperature, (neither number of moles of solute nor mass of solvent will be affected
by changes of temperature), while molarity changes as temperature changes(volume
of solution changes as temperature changes).
Answer:
<u><em>Solar panels don't work for every type of roof</em></u>
<u><em>Solar isn't ideal if you're about to move</em></u>
<u><em>If your electricity costs are low, so are your solar savings</em></u>
<u><em>If you can't access solar financing, up-front solar costs can be intimidating</em></u>
<u><em>High initial costs for material and installation and long ROI (however, with the reduction in cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank</em></u>
<u><em>Besides cost, the single biggest problem with solar is that the sun doesn't shine at night, and it's not guaranteed that it will shine during the day either. This causes several problems, which can be summed up in you not having power when the day ends</em></u>
