Problem PageQuestion A chemistry student needs 10.0g of dimethyl sulfoxide for an experiment. By consulting the CRC Handbook of
PIT_PIT [208]

Answer:

9.09cm3

Explanation:

The following data were obtained from the question:

Mass of dimethyl sulfoxide = 10g

Density of dimethyl sulfoxide = 1.10gcm−3

Volume of dimethyl sulfoxide =?

The density of a substance is simply the mass substance per unit volume of the substance. It is represented mathematically as:

Density = Mass/volume.

With the above formula, we can obtain the volume of dimethyl sulfoxide as follow:

Density = Mass/volume

1.10gcm−3 = 10g/ volume

Cross multiply to express in linear form

1.10gcm−3 x Volume = 10g

Divide both side by 1.10gcm−3

Volume = 10g / 1.10gcm−3

Volume = 9.09cm3

Therefore, the volume of dimethyl sulfoxide the student should pour out is 9.09cm3

What is the pH of a solution of RbOH with a concentration of 0.86 M? Answer to 2 decimal places
lubasha [3.4K]

Answer:The pH of the solution is given by pH=−log([H3O+])

Explanation:so you can't use

pH

=

−

log

(

0.150

)

because that's the concentration of the hydroxide anions,

OH

−

, not of the hydronium cations,

H

3

O

+

. In essence, you calculated the

pOH

of the solution, not its

pH

.

Sodium hydroxide is a strong base, which means that it dissociates completely in aqueous solution to produce hydroxide anions in a

1

:

1

mole ratio.

NaOH

(

a

q

)

→

Na

+

(

a

q

)

+

OH

−

(

a

q

)

So your solution has

[

OH

−

]

=

[

NaOH

]

=

0.150 M

Now, the

pOH

of the solution can be calculated by using

pOH

=

−

log

(

[

OH

−

]

)

−−−−−−−−−−−−−−−−−−−−

In your case, you have

pOH

=

−

log

(

0.150

)

=

0.824

Now, an aqueous solution at

25

∘

C

has

pH + pOH

=

14

−−−−−−−−−−−−−−so you can't use

pH

=

−

log

(

0.150

)

because that's the concentration of the hydroxide anions,

OH

−

, not of the hydronium cations,

H
