10.41 grams NH3 X (1 mol/17.00 grams) = 0.612 moles NH3 X (3 mol H2 / 2 mol NH3) = 0.918 moles H2. 0.918 mol H2 X 2.01 g/mol = 1.85 grams H2 required. 7.94 X 10^-4 g H2 X (1 mol/2.01 grams) = 0.93.95 X 10^-4 mol H2 X (2 mol NH3 / 3 mol H2) = 2.63 X 10^-4 moles NH3.

Tear or Sprain. -. Sprains, strains and tears are different types of injuries, and it's important to know how they differ, a sports massage therapist says. A sprain is the overstretching or tearing of ligaments, which are the tissues that connect bones to each other and stabilize them. Sprains occur when the joint is forced into an unnatural position. They happen most often in the ankle but can occur at any joint, such as the wrist or knee, said Martin Mufich.
