The weight of one atom of uranium is 238amu.its actual weight is
1 amu = 1.6605E-24g
WOULD YOU WANT TO BE A SILICON RIBBON TWIRLER? (10/10 points)
A silicon ribbon measuring 100 micron thick, 5 mm wide, and 1 m long has 5 volts applied across its long dimension. The resistivity of silicon is 640 ohm-m. How much current will flow through the ribbon? Express your answer in Amps.
3.906*10^-9 - correct
3.906⋅10−9
To determine the actual weight of one atom of uranium, we need to convert atomic mass units (amu) into a more commonly used unit, such as grams.
The conversion factor between atomic mass units and grams is based on the definition that one mole of any substance contains 6.022 × 10^23 entities (Avogadro's number).
1 amu = 1 gram per mole (g/mol)
So, the weight of one atom of uranium can be calculated as follows:
Weight of one atom of uranium = (238 amu) x (1 gram/1 amu)
Weight of one atom of uranium = 238 grams
Therefore, the actual weight of one atom of uranium is 238 grams.
