<u>Given:</u>
Volume of 0.9% NaCl = 500 ml
Time (t) = 4 hrs
<u>To determine:</u>
The infusion rate of NaCl in ml/hr
<u>Explanation:</u>
Based on the information- 500 ml of NaCl is to be given over a time span of 4 hrs
Hence, the volume of NaCl to be administered per hr is:-
= 1 hr * 500 ml/4 hr = 125 ml
Ans: Infusion rate = 125 ml/hr
Hey there!:
moles of NaOH = 10.1 / 40 = 0.2525
heat = ΔH x moles
= 44.4 x 0.2525
= 11.21 kJ
total mass = 10.1 + 250 = 260.1 g
Q = m Cp dT
11211 = 260.1 x 4.18 x dT
dT = 10.3
T2 = 10.3 + 23 = 33.3 °C
temperature = 33.3 ºC°
Hope this helps!
