Isotopes have same atomic number but different atomic mass number.
Hence option B is correct.
Hope this helps you!
density of the object = 0.53 g/mL
Explanation:
First we need to find the volume of the object which is equal to the rise of the water in the graduated cylinder:
volume = 31.7 - 25.1 = 6.6 mL
Now we calculate the density of the object using the following formula:
density = mass / volume
density = 3.5 g / 6.6 mL
density = 0.53 g/mL
