The most commonly used transistor configuration is the NPN Transistor. We also learnt that the junctions of the bipolar transistor can be biased in one of three different ways – Common Base, Common Emitter and Common Collector.
In this tutorial about bipolar transistors we will look more closely at the “Common Emitter” configuration using the Bipolar NPN Transistor with an example of the construction of a NPN transistor along with the transistors current flow characteristics is given below.
Is 2.0 x 10 to the -9th power an option
Answer: The molecular weight of tris buffer is 121 g/mol
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
moles of tris buffer =
Now put all the given values in the formula of molality, we get
Therefore, the molecular weight of tris buffer is 121 g/mol
