Answer:
i. Molar mass of glucose = 180 g/mol
ii. Amount of glucose = 0.5 mole
Explanation:
<em>The volume of the glucose solution to be prepared</em> = 500 
<em>Molarity of the glucose solution to be prepared</em> = 1 M
i. Molar mass of glucose (
) = (6 × 12) + (12 × 1) + (6 × 16) = 180 g/mol
ii.<em> mole = molarity x volume</em>. Hence;
amount (in moles) of the glucose solution to be prepared
= 1 x 500/1000 = 0.5 mole
You can wait until he either breaks up (if he does) or if just forget about him and go for another guy.
Answer:
Its ability to denature bacterial proteins
Explanation:
Ethanol is a rapid antimicrobial against bacteria, fungi and viruses. When 70% concentrated Ethanol is in contact with a single celled organism, the it coagulates the protein at a slower rate, creating enough time for it to penetrate the cell before coagulation can block it.This will make the whole cell coagulated thus killing the cell.
