Value: 4 The equation of a line for Data Set 4 is y = 0.14*x + -0.0398 where y is the absorbance
values and x is the concentration in mg/mL. This was created using data from known
concentrations and absorbances. Now we can use this equation of a line to determine
the concentration of an unknown solution.
Determine the concentration of an unknown solution that has an absorbance of 0.622.
Concentration =
mg/mL. Use two sig figs in your final answer
= 1/2

In meteorology, a  cloud  is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. nephology is the science of  clouds, which is undertaken in the  cloud  physics branch of meteorology.cirrus clouds  usually describe clouds high in the atmosphere that can include wispy clouds, typically with ice crystals. variations include cirrus, cirrocumulus and cirrostratus as defined by the cloud's position in the atmosphere.layered stratus clouds  have both flat tops and bases, and can appear as if they take up the whole sky, stretching from horizon to horizon. other combinations and variations include stratus, stratocumulus, nimbostratus and altostratus.cumulus clouds  often pile up in multiple layers of the atmosphere, representing clouds that develop vertically. cumulus clouds often look like pillars with anvil-type tops or columns of clouds stacked vertically. variations include cumulus, cumulus-congestus, cumulonimbus and altocumulus.

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"
