The molecular weight of oxygen gas is 32 grams per mole, and we calculate the weight of the atmosphere based on this estimate.
Solution:
PV = ART
6.30 x 1.95 = n x 12.285 × 290
n = 0.6226 moles.
The molar weight of oxygen gas is 32 grams, mol on which to estimate the atmospheric weight.
Irregular Edges Edges are often jagged chipped or blurred. The pigment can spread to the surrounding skin. Uneven Colors Black brown and tan shades may be present. White, gray red, pink, or blue areas can also be seen.
If the mole is larger than other moles has dirty or uneven edges is uneven in color, or is slightly pink see a doctor for an examination. please give me. Bruises that appear in adulthood should be checked. However, the most worrying sign is the change in the mole. Experts believe that genetic factors, hormonal changes, and sun damage can cause new moles to suddenly appear, but no one knows for sure.
