<span>600 grams.
2,5 times 240 yields a result of 600 ml in 2.5 cups. A milliliter is equal to a cubic centimeter of liquid. As water has a mass of 1 gram per cubic centimeter, 600 milliliters of water has a mass of 600 grams.</span>
Answer: The vapor pressure of the solution at 
is 29.86 mm Hg
Explanation:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= relative lowering in vapor pressure
i = Van'T Hoff factor = 1 (for non electrolytes)
= mole fraction of solute
=
Given : 9 moles of 
are dissolved in 50 L or 50000 ml of water
mass of water = 
moles of solvent (water) = 
Total moles = moles of solute + moles of solvent = 9 mol + 2778 mol = 2787
= mole fraction of solute
=
Thus the vapor pressure of the solution at is 29.86 mm Hg
They work by reducing the acid in our stomach because anti acids alkalis.
Answer:
Hydrosulfuric acid will act as limiting reactant.
Explanation:
Given data:
Mass of iron(III) chloride = 3243.0 g
Mass of hydrosulfuric acid = 511.8 g
Limiting reactant = ?
Solution:
Chemical equation:
2FeCl₃ + 3H₂S → Fe₂S₃ + 6HCl
Number of moles of iron(III) chloride:
Number of moles = mass/molar mass
Number of moles = 3243.0 g/ 162.2 g/mol
Number of moles = 20 mol
Number of moles of hydrosulfuric acid:
Number of moles = mass/molar mass
Number of moles = 511.8 g/ 34.1 g/mol
Number of moles = 15 mol
Now we will compare the moles of both reactant with products
FeCl₃ : Fe₂S₃
2 : 1
20 : 1/2 ×20 = 10
FeCl₃ : HCl
2 : 6
20 : 6/2 ×20 = 60
H₂S : Fe₂S₃
3 : 1
15 : 1/3 ×15 = 5
H₂S : HCl
3 : 6
15 : 6/3 ×15 = 30
Hydrosulfuric acid producing less number of moles of product thus, it will act as limiting reactant.
