M1V1 = M2V2

M1: is the molarity of the solution before dilution.

V1: is the volume of the solution that we need to dilute.

M2: is the molarity of the solution after dilution.

V2: is the volume of the solution after dilution.

By substitution;

12*V1 = 3*5

V1 = 1.25 litters.

In the combined gas law, if the pressure in the system is increased, what happens to the volume if temperature remains constant?

[ad_2]

[ad_1]

**Answer:- The pressure ‘p’ will be infinity at volume ‘V’=0.**

**Explanation:- **

The given equation :- where p is a rational function dependent on V.

**A rational function is undefined for denominator = 0.**

In the given function V is the denominator , if V=0 then the function will be undefined.

⇒ p will approach to zero at V=0.

For assistance see the attachment , the graph of the given function represented by vertical assymptote which approaches to 0 but never touches it..

Which Hellenistic inventor and mathematician experimented with levers, created a machine for raising and transporting water and determined formulas for calculating the surface area and volume of a sphere?

[ad_2]

[ad_1]

**Answer with Step-by-step explanation:**

The volume of a rectangular pyramid is given by:

V=lbh/3

Where l is the length

b is the breath

and h is the height.

Now, l’,b’ and h’ be new length,breath and height

Then, l’=3l

b’=b

and h’=h/7

New volume=V’=l’b’h’/3

=

=

**Hence, Volume formula which reflects these changes is:**

To calculate the pH of this solution, we use the

Henderson-Hasselbalch equation:

pH = pKa + log ([A-]/[HA])

Where,

[A-] = Molarity of the conjugate base =

CH3COO- = 0.29 M

[HA] = Molarity of the weak acid = CH3COOH = 0.18 M

pKa = dissociation constant of the weak acid =

4.75

When KOH is added to the buffer, the chemical

reaction is:

CH3COOH + KOH = CH3COO-K+ + H2O

Therefore when 0.0090 mol KOH is added, 0.0090

mol acid is neutralized, and 0.0090 mol CH3COO- is produced.

[CH3COO-] = [0.0090 mol + 0.375 L (0.29 mol/L) ]

/ 0.375 L = 0.314 M

[CH3COOH] = [-0.0090 mol + 0.375 L (0.18 mol/L) ]

/ 0.375 L = 0.156 M

Going back to Henderson-Hasselbalch

equation:

pH = 4.75 + log (0.314 / 0.156)

**pH = 5.054**

P1V1 = P2V2

P1 is the pressure of the gas in the first case.

V1 is the volume of the gas in the first case.

P2 is the pressure of the gas in the second case.

V2 is the volume of the gas in the second case.

P1 = 0.890 atm, V1 = 5.75l

a. P2 = 1.25 atm,

0.890*5.75 = 1.25*V2

V2 = 4.094 l

b. P2 = 0.350 atm,

0.890*5.75 = 0.350*V2

V2 = 14.621 l.

Water footprint is the measurement of the amount of fresh water utilized in the production or supply of the goods and services used by a particular person or group. The water footprint tells us how much water is used in a single process (for example: production of one T-Shirt, but it is also an indicator for the amount of water consumed by a particular country or nation.

So, our water footprint includes the volume of freshwater we use both directly and indirectly.
