You just have to convert the mass of water into volume.
To do that you use the density of water, which is about 1.0 g/ ml
So, from the formula of density D = M / V, you get V = M / D
=> V = 2.49 * 10^7 grams / 1.0 g / ml = 2.49 * 10 ^ 7 ml
You can pass that to liters using the conversion factor 1000 ml = 1 l
2.49 * 10^7 ml * 1 l / 1000 ml = 2.49 * 10^4 l = 24,900 l
Answer: 24,900 l
C. ) Fullerene has the shape like soccer ball
Answer:
Boiling of a substance
Explanation:
When something is boiled, heat is released to the surrounding, making it an exothermic reaction (a type of chemical reaction)
The amount of KCl that would be formed will be 478.8 grams
<h3>Stoichiometric calculations</h3>
From the equation of the reaction, the mole ratio of K to
is 2:1.
Mole of 309 g potassium = 309/39 = 7.92 moles
Mole of 228 g Cl2 = 228/71 = 3.21 moles
Thus, potassium is in excess while Cl2 is limiting.
Mole ratio of Cl2 and KCl = 1:2
Equivalent mole of KCl = 3.21 x 2 = 6.42 moles
Mass of 6.42 moles KCl = 6.42 x 74.55 = 478.8 grams
