Answer:

The atomic mass of lead is: 207.216 u

Explanation:

data                 Isotopes                     mass                      percent

                             1                      203.97302                      1.4

                             2                     205.974444                    24.1

                            3                      206.97587                       22.1

                            4                      207.97663                       52.4

atomic mass = (203.97302x 0.014) + (205.974444 x 0.241) +

                        (206.97587 x 0.221) + (207.97663 x 0.524)

atomic mass = 2.856 +49.639 + 45.742 + 108.979

atomic mass = 207.216 u

Water difference between glacier and geyser
Gekata [30.6K]
Glaciers are found in areas where the net accumulation of snow exceeds the melt, therefore they are usually found in areas of high elevation, cold temperatures, and high precipitation.

Geysers are found in areas of shallow crust with high heat flow, such as hot spots.
