The mass of substance consumed in g to provide a lethal dose is 62.496 g
The substance has an LD50 of 336 mg/kg. We require the number of grams of the substance that a 186 kg person would consume to reach the probable lethal dose.
So, mass of substance consumed = lethal dose × mass of person
lethal dose = 336 mg/kg and mass of person = 186 kg
mass of substance consumed = lethal dose × mass of person
mass of substance consumed = 336 mg/kg × 186 kg
mass of substance consumed = 62496 mg
Converting to g, we have
mass of substance consumed in g = 62496 mg × 1 g/1000 mg = 62.496 g
So, the mass of substance consumed in g to provide a lethal dose is 62.496 g

Answer:
Explanation:
In an acid-catalyzed epoxide ring-opening reaction, there is a formation of two intermediate in the reaction. The first stage involves the protonation of oxygen in the epoxide. The stage is followed by the attraction of water molecules onto the more substituted carbon atom in the epoxide ring. The stepwise reaction mechanism can be seen in the image attached below.
Answer:
Yes it is
Explanation: because it is composed of identical molecules consisting of atoms of two or more chemical elements.

If you mean LiOH+HBr->LiBr+H2O
the answer is 0.4347mol LiBr and that equals (10/23)/80 gram LiBr
