It's one of the givens of kinetic molecular theory. It explains why hydrogen gas diffuses faster than carbon dioxide. Thus there is a greater probability that a lighter molecule like hydrogen will be able to cross a given transient empty space faster than a heavier one before the gap, so to speak, closes up.
(<60 kg) for IM injection in the deltoid muscle only if the subcutane-. ous tissue is not bunched and the injection is made at a 90Â° angle; a 1 needle is sufficient in adults weighing 130â152 lbs (60â70 kg);
Each 0.5 mL dose is to be injected intramuscularly using a sterile needle attached to the supplied prefilled syringe. The preferred sites for injection are the anterolateral aspect of the thigh in infants and the deltoid muscle of the upper arm in toddlers, children and adults.ach 0.5 mL dose is to be injected intramuscularly using a sterile needle attached to the supplied prefilled syringe.
