Answer:
0.2558 g
Explanation:
1.- In titration, since you have the concentration and the volume of the titrant and the aliquot that you take, you can use the formula C1 V1 = C2 V2.
2.- To obtain C2 = C1 V1 /V2
Substitution C2 = (0.0149 M ) (9.75 ml) /25 ml = 0.0058 11 M
3.- This concentration is the number of moles that you would have in 1 L but you dissolve your tablet in 250 ml, so a rule of three.
4.- 0.005811 moles - 1 L
x - 0.250 L
X= 0.250 L x 0.005811 moles / 1L = 0.00145275 moles
5.- using your molecular weight, you can obtain the grams with another rule of three.
0.00145275 moles - x
1 mole - 176.12 g
x= 176.12 g x 0.00145275 moles / 1 mole = 0.2558 g

A patient with these features has a cardiac output of 2,800 mL/minute. Cardiac output can be calculated by using oxygen consumption and oxygen level in the blood.
<h3>What is cardiac output?</h3>
The cardiac output refers to the rate at which blood cells are pumped by the heart to the rest of the body.
The cardiac output can be calculated as oxygen consumption divided by oxygen concentration in arteries multiplied by the oxygen level in venous blood.
This measure (cardiac output) is fundamental to calculate the blood pumped by the hearth.
