Answer: 0.18 M

Explanation:

Initial molarity, M1 = 0.8 M

Initial olume, V1 = 225 ml

Final volume, V2 = 1000 ml

Final Molarity, M2 = M1V1/V2

= 0.8 x 225/1000

= 0.18 M

What is the density of a 19.3-gram object that displaces 12 cubed centimeters of water
KIM [24]

Answer:

1.608 g/cm3

Explanation:

Formula:

D=m/v

d= density

m= mass

v= volume

Given data:

Mass= 19.3 g

Volume= 12 cm3

The volume of water displaces by object is 12 cm³ which means that object hold the volume of 12 cm³

Now we will put the values in formula:

D=19.3 g/ 12 cm3= 1.608 g/cm3

so the density of object is 1.608 g/cm3

Which is the strongest acid? Ch3ch2ch2chfch2co2h ch3ch2ch2cbr2ch2co2h ch3ch2ch2cf2ch2co2h ch3chbrch2ch2ch2co2h ch2clch2ch2ch2ch2
liq [111]

The strength of an acid increases if the stability of conjugate base increases

The stability of a conjugate base increases with the presence of electron with drawing group (electronegative group)

Thus more the electronegativity of an atom attached to a carboxylic acid higher the strength of acid

In these examples CH3CH2CH2CF2CH2COOH contains to electronegative flourine atoms which stabilizes the conjugate base hence this will be the strongest acid among the given acids
