Non-explosive, so I wouldn't have to worry about is exploding at a random time and I would know I was safe.
Answer:
2.107×10²⁴
Explanation:
no of moles=no of particles/Avogadro's number
3.5=X/6.02×10²³
by cross multiplication
3.5×6.02×10²³
=2.107 ×10²⁴
Answer:
C3H6O3
Explanation:
To find the emperical of the compound,you divide the percentage composition of each element by it's molar mass(C=12, H=1, O=16).
For C,40/12=3.33. For H,6.71/1=6.71
For O,53.19/16=3.33.
Then divide everything by the smallest value which is 3.33
For C,3.33/3.33=1. For H,6.71/3.33=~2.
For O,3.33/3.33=1.
Emperical formula=CH2O
Molecular formula=(CH2O)n=90
(12+2*1+16)n=90
30n=90, n=3
molecular formula=(CH2O)3
molecular formula of lactic acid=C3H6O3.
The strong electrolyte KF completely dissociates into K+ and
F- ions when it dissolves in water. When the weak electrolyte HF dissolves in
water, there are a few ions of H+ and F- present, but mostly dissolved HF
molecules. I am hoping that this answer has satisfied your query
and it will be able to help you in your endeavor, and if you would like, feel
free to ask another question.
