Answer: There are molecules present in 6.71 moles of
.
Explanation:
Given: Moles of = 6.71 mol
According to the mole concept, 1 mole of every substance contains molecules.
Therefore, molecules present in 6.71 moles are calculated as follows.
Thus, we can conclude that there are molecules present in 6.71 moles of
.
Answer:
17 ohms
Explanation:
Given that,
In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance.
We need to find the total resistance of the circuit.
The equivalent resistance for series combination is given by :
For 17 light bulbs, the equivalent resistance is given by :
Hence, the total resistance is 17 ohms. Hence, the correct option is (d).
