Answer:
Molarity= 1.69M
Explanation:
m= 14.8, Mm= 35, V= 0.25dm3, C= ?
Moles = m/M= C×V
Substitute and Simplify
m/M= C×V
14.8/35= C×0.25
C= 1.69M
Answer:
mass of sulfur = 96 g
Explanation:
no of moles of sulfur dioxide in molecules =
= 2 moles
therefore mass of sulfur dioxide = moles×atomic number
=2×(16+32)
=96
Answer:
B. The rate constant is the reaction rate divided by the concentration
terms.
Explanation:
The rate constant can be determined from the rate law because it is the reaction rate divided by the concentration terms. I hope I could help! :)
