Hemoglobin is the protein responsible for transporting O2 throughout the body. Each molecule of hemoglobin combines with four molecules of O2. If 1.22 g of hemoglobin combines with 1.53 mL of O2 at 37 °C and 743 torr, what is the molar mass of hemoglobin based on this experiment?

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m

100cm, because 11.0 cm is 3 figures as they've chosen to include the decimal point. if you have a 3 digit number then anything after the second digit will become 0 if it's to 2 significant figures
