2C3H7OH + 9O2 → 6CO2 + 8H2O
Answer:
The correct answer is 4.16 grams.
Explanation:
Based on the given information, the concentration of KCl solution is 16 % m/v, which means that 100 ml of the solution will contain 16 grams of KCl.
The molarity of the solution can be determined by using the formula,
M = weight/molecular mass × 1000/Volume
The molecular mass of KCl is 74.6 grams per mole.
M = 16/74.6 × 1000/100
M = 16/74.6
M = 2.14 M
Now the weight of KCl present in the solution of 26 ml will be,
2.14 = Wt./74.6 × 1000 /26
Wt. = 4.16 grams
0.0082 You have to equal out the amount of concentration with the unknown
Answer:
a it rarely reach with other elements
Answer:
270
Explanation:
Once you add more mass to something the mass doesn’t go away you add more mass.
hope this helps!
