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

Answer:2
I think its 2 because when you get the loan you should see the intrest rates instead of getting an big or small amount to use immediately
<h3> Number = 23</h3>
<h2>Step-by-step explanation:</h2>
<h3>Given:</h3>
Six is subtracted from a number.
The result is equal to one fourth of the sum of the number and 45 find the number .
<h3 /><h3>To Find:</h3>
What is the number ?
Solution: Let the number be x.
➟ Subtracting 6 from x.
➟ (x – 6) ㅤㅤㅤㅤㅤ(eqⁿ 1)
Now,
➙ One fourth of sum of the number + 45
➙ 1/4 × x + 45
➙ x + 45/4ㅤㅤㅤㅤ(eqⁿ 2)
According to the question,
Equation 1 = 2
⟹ (x – 6) = x + 45/4
⟹ 4(x – 6) = x + 45
⟹ 4x – 24 = x + 45
⟹ 4x – x = 45 + 24
⟹ 3x = 69
⟹ x = 69/3
⟹ x =23
Hence, the number is 23.
Evaluate at least 200 spermatozoa, tally the numbers of live and dead spermatozoa using a laboratory counter, and calculate the percentage of live spermatozoa (see Note 10). The lower reference limit for vitality assessed by eosin–nigrosin stain (membrane-intact spermatozoa) is 58% (5th percentile, 95% CI 55–63) (1).
