Chemistry

From the given density, 19.3 g/cm³, every cubic centimeter of tungsten (W) has a mass of 19.3 grams. Determine the amount of substance in moles by dividing the mass by the molar mass,
                             (19.3 g) x (1 mole/ 183.84 g) = 0.1044 moles
The number of atoms is calculated by multiplying the amount in moles by the Avogadro's number.
                     (0.1044 moles) x (6.022x10^23 atoms / moles) = 6.29x10^22 atoms. 
Thus, there are approximately 6.29x10^22 atoms of W.

As you used two diferent instruments, one is more sensitive than the other.

Explanation:

The sensitivity of an instrument is the minimum amount of magnitude that can be  differentiate a measurement system.

In method A, you got 27 cm, so if in method B, you got 27.00, method B is more sensitive. It's like saying that one system measures more than the other
