Why would a scientist want to replicate another scientist's experiment?

See the answer below

Explanation:

A scientist B might want to replicate the experiment of another scientist A in order to assess the claims made by scientist A. In other words, replication of the experiment of another scientist is done to see if a similar outcome would be arrived at or there would be variations.

The claims made by a scientist while reporting the outcome of a particular experiment must be reproducible by another scientist under similar conditions. Otherwise, the claims are said to be false.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
