A chemical formula is obtained from the number of atoms in a compound.

Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.

For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

A pharmaceutical company claimed that experiments showed that its drug could effectively reduce the growth of cancer cells by 35
Mazyrski [523]
<span>The labs were unable to reproduce the pharmaceutical company’s data

In this case, assuming that the laboratories followed the same procedure as the pharmaceutical company, the fact that the data could not be replicated means that the company's claims are invalid. The validity of the claims is more questionable given the huge difference in the final conclusions, with the company reporting a 35% decrease, while the maximum decrease observed by the labs was 8%.
