Answer: 18g
Explanation:
1 mle of glucose combusts to give 6moles of CO2 and 6moles of H2O
C6H12O6 + 6O2-------- 6CO2 + 6H2O at STP.
Multiplying 6 by 3 moles we have 18 g of CO2
Answer:
72 g/L
Explanation:
The dissolved amount of solute is the difference between the amount you have poured and the amount that precipitated:
125 g - 35 g = 90 g
Thus, 90 grams of solute were dissolved in 1.25 liters. The saturation point is the ratio between the grams dissolved and the volume in liters:
saturation point = 90 g/1.25 L = 72 g/L
