Answer:
0.30M HOAc
Explanation:
Given 250.0ml (0.96M HOAc) => 800ml(??M HOAc)
Use the dilution equation...
(Molarity x Volume)concentrated soln = (Molarity x Volume)dilute soln
(0.96M)(250.0ml) = (Molarity diluted soln)(800ml)
Molarity diluted soln = (0.96M)(250.0ml)/(800ml) = 0.30M HOAc
Answer: I think it's 1
Explanation: Potential energy means stored energy . In Position 1 it's not moving the energy is being stored. Hope that helps.

B
Explanation:
Genetics,mutations over time
This is the answer because on biology you have all those kind of questions
Pls mark brainlist
The number of moles of nitrogen gas is 1.0 mole
<u><em>calculation</em></u>
N2 is a molecule therefore;
1 molecule of N₂ = 2 atoms of N
? molecules= 1.2 x10 ²⁴atoms
<em>by cross multiplication</em>
=[( 1.2 x 10²⁴ atoms x 1 molecule) / 2 atoms] = 6 x 10²³ molecules
According to Avogadro's law 1 mole =6.02 x 10²³ molecules
? moles= 6.0 x 10²³ molecules
<em>by cross multiplication</em>
= [(6.0x 10²³ molecules x 1 mole) / 6.02 x10²³ molecules] = 1.0 mole
