Answer:
The answer to your question is 43.9 g of NaCl
Explanation:
Data
Grams of NaCl = ?
Volume = 0.75 L
Molarity = 1 M
Number of moles = ?
Formula
Solve for number of moles
Number of moles = Molarity x volume
Substitution
Number of moles = 1 x 0.75
= 0.75
Molecular weight of NaCl = 23 + 35.5 = 58.5
Calculate the grams of NaCl using proportions
58.5 g of NaCl ---------------- 1 mol
x ---------------- 0.75 moles
x = (0.75 x 58.5) / 1
x = 43.9 g of NaCl
Answer:
A) 1
B) 2.5
C) 3.32
Explanation:
The possibility of n=1 is not achievable in 20 minutes and 30 minutes as calculated n=1 for 10 minutes. The same conversion cannot be achieved for the rest of the time which is impossible as 75% conversion and it cannot be achieved at 10 min and 20 min at the same time
A) what is the order of the reaction if it takes 10 minutes to reach 75% conversion
= n ( order ) = 1
B) what is the order of reaction if it takes 20 minutes to reach 75% conversion
= n ( order ) ≈ 2.5
C) what is the order of reaction if it takes 30 minutes to reach 75% conversion
= n ( order ) ≈ 3.32
