Molarity= moles/ liters
first you need to calculate the moles using the molar mass of the molecule to convert grams to moles
molar mass MgO= 40.3 grams/ mole
62.5 gram MgO (1 mole/ 40.3 grams)= 1.55 mole
Molarity= 1.55 mole/ 1.50 Liters= 1.03 M
Answer:
MAC: Assembly of the MAC leads to pores that disrupt the cell membrane of target cells, leading to cell lysis and death
Interferons: Stimulates the infected cells and those nearby to produce proteins that prevent the virus from replicating within them
Cytokines: Molecular messengers between cells

Answer:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

Answer:
salt is weaker and has looser atomic bonds and iron has stronger and tighter ionic bonds
Explanation:
First we will calculate the number of moles of Iron:
, where n is the number of moles, m is the mass of iron in the reaction and M is the Atomic weight.
moles of Iron.
The same number of moles of Oxygen will take part in the reaction.
So
where 32 is the Atomical Weight of Oxygen (16 x 2).
=>
g
