assuming that 1g of aspirin dissolves in 450ml of water at 10°C,how much aspirin would be lost in the 5ml of water added to the reaction mixture if the mixture were at 10°C,durin filtration?

see above.

0.01

where is the working?

1g >45o ml

X>50 ml
50 ml g =450 ml x
We divide by 450
Then the answer will be 0.01g

To determine how much aspirin would be lost in the 5ml of water added to the reaction mixture during filtration, we need to calculate the solubility of aspirin at 10°C and compare it to the amount of water used.

1. Convert the given solubility from grams per milliliter (g/ml) to grams per liter (g/L):
1g/450ml = (1g/450ml) * (1000ml/1L) = 2.22g/L

2. Calculate how much aspirin can be dissolved in 5ml of water at 10°C:
2.22g/L * (5ml/1000ml) = 0.0111g

Therefore, if 5ml of water were added to the reaction mixture at 10°C, the amount of aspirin that could be lost during filtration would be approximately 0.0111 grams.
