Answer:
![V_1=23.3~mL](https://tex.z-dn.net/?f=V_1%3D23.3~mL)
Explanation:
In this case, we have a dilution problem. We have to remember that in the dilution procedure we go from a solution with higher concentration to a solution with lesser concentration. Therefore we have to start with the dilution equation:
![C_1*V_1=C_2*V_2](https://tex.z-dn.net/?f=%20C_1%2AV_1%3DC_2%2AV_2)
Now we can identify the variables:
![C_1=~1.475_M](https://tex.z-dn.net/?f=C_1%3D~1.475_M)
![V_1=~?](https://tex.z-dn.net/?f=V_1%3D~%3F)
![C_2=~0.1374_M](https://tex.z-dn.net/?f=C_2%3D~0.1374_M)
![V_2=~250.0~mL](https://tex.z-dn.net/?f=V_2%3D~250.0~mL)
If we plug all the values into the equation:
![1.475_M*V_1=0.1374_M*250.0~mL](https://tex.z-dn.net/?f=1.475_M%2AV_1%3D0.1374_M%2A250.0~mL)
And we solve for
:
![V_1=\frac{0.1374_M*250.0~mL}{1.475_M}](https://tex.z-dn.net/?f=V_1%3D%5Cfrac%7B0.1374_M%2A250.0~mL%7D%7B1.475_M%7D)
![V_1=23.3~mL](https://tex.z-dn.net/?f=V_1%3D23.3~mL)
I hope it helps!
Answer:
Part A:
"360 grams of NaCl can be dissolved in 1 L water. So, 2000 grams sugar can be dissolved in 1 L water then we can say that the solubility of salt is lesser in water as to sugar and both heightened by increasing the temperature. If we make a batch of 800 L we can add sugar, 1600 kg at 25 0c. We can add salt is 288 kg at 25 0c and the ingredient tomato is having low solubility."

From the question you will find that:
one capsule of tamiflu is obtained from 2.6 g of star anise.
1 capsule = 2.6 g tamiflu
? capsules = 155 g tamiflu
by cross multiplication =
![\frac{(1 x 155)}{2.6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%281%20x%20155%29%7D%7B2.6%7D%20)
= 59 capsules
