Answer: The mass of 0.5 mole of element ab is 81.67 g.
Explanation:
According to the mole concept, 1 mole of a substance contains . As, the mass of atoms is 0.49 g.
So,
Therefore, mass of 1 mole =
= 163.33 g/mol
Hence, mass of 0.5 mole of ab element is calculated as follows.
= 81.67 g
Therefore, the mass of 0.5 mole of element ab is 81.67 g.

Answer:
11.4 m
Explanation:
We are given that
Total distance traveled by cab,d=214 m
Maximum speed of cab=v=315 m/min=
1 min =60 s
Acceleration of cab=
We have to find the distance traveled by the cab while accelerating to full speed from rest.
Initial speed o f cab=u=0
Substitute the values in the formula
Hence, the cab travel 11.4 m from rest to full speed.
