5000 units of antigens are present in 0.5 mL of the mumps virus vaccine.
Volume of the vaccine after dilution with water = 2 mL
0.5 mL has 5000 units antigen. So when 0.5 mL was diluted to 2 mL, the final vaccine after dilution would contain 5000 units of antigen.
Units of antigen present in 1 mL vaccine sample
=
Therefore, 2500 units of the antigen will be present in each milliliter, if 0.5 mL of the vaccine is diluted to 2 mL with water for injection.
2 C5H12O + 15 O2 = 10 CO2 + 12 H2O
Hope this helped :)
Explanation:
temperature changes affect seawater density as water cools its density increases. As water cools H2O molecules pack more closely together because the molecules are vibrating less at low temperatures and take up less volume. The same number of water molecules in smaller volume results higher density
Since a burning fire, a racing car, and boiling water all demonstrate kinetic energy, the correct answer is a chemical bond, which exhibits potential chemical energy.
Hope this helps.
