The solution to your problem is as follows:
<span>2 KClO3 → 2 KCl + 3 O2
</span><span>MW of KCL = 39.1 + 35.35 = 74.6 g/mole
62.6/74.6 = 0.839 moles KCl produced
0.839 moles KCl x 3O2/2KCl x 32g/mole O2 = 40.27g of O2 was produced
</span>
Therefore, there are <span>40.27g of O2 produced during the reaction.
</span>
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
Answer:
The concentration will be 0.352 M
Data Given
mass of calcium fluoride = 27.5 g
molar mass of calcium fluoride = 78.07 g/mol
Volume = 1.0 L
Solution:
Molarity = given mass÷ molar mass) × (1 ÷ vol (L) )
Molarity = (27.5 ÷ 78.07)× (1 ÷ 1) = 0.352 M
Download the app called Socratic it helps with these problems
He concluded that elecotrons was found in all atoms.:) hope i helped
It's around two feet, although I'm not sure how you can express that in 1 word. If you use the metric system it's about 0.6 metres.
