(h) Mass: 6.02×1023 atoms of 235U or 6.02 × 1023 atoms of 238U
ANSWER:
Solution 89P
Here we have to identify among that the given pair, which one is larger or the samples are equal:
Step 1
(a) Entities: 0.4 mol of O3 molecules or 0.4 mol of O atoms
Number of entities = no. of moles
0.4 mol of O3 = 0.4 mol= 2.4 1023 entities
0.4 mol of O atoms = 0.4 mol= 2.4 1023 entities
Thus the given samples are equal.
