Answer: The volume of stock solution needed is 62.5 mL

Explanation:

A solution consists of solute and solvent. A solute is defined as the component that is present in a smaller proportion while the solvent is defined as the component that is present in a larger proportion.

To calculate the volume of stock solution needed, the formula used is:

[tex]C_1V_1=C_2V_2[/tex] ....(1)

where,

[tex]C_1\text{ and }V_1[/tex] are the concentration and volume of stock solution.

[tex]C_2\text{ and }V_2[/tex] are the concentration and volume of diluted solution.

We are given:

[tex]C_1=3.00M\\V_1=?mL\\C_2=1.25M\\V_2=150mL[/tex]

Putting values in equation 1, we get:

[tex]3.00\times V_1=1.25\times 150\\\\V_1=\frac{1.25\times 150}{3.00}\\\\V_1=62.5mL[/tex]

Hence, the volume of stock solution needed is 62.5 mL

Answer:

36kcal

Explanation:

There are three things that occur in the process not converting ice to steam. They are;

I) fusion of ice

ii) heating of water to 100°C

iii) vaporization of water at 100°C to yield steam

Hence, total heat required to convert ice to steam=

Latent heat of fusion of ice + heat required to raise the temperature of water to 100°C + Latent heat of vaporization of water

Thus;

H= mLfus + mcθ + mLvap

H= m(Lfus + cθ + Lvap)

H= 50(80 + 1(100) + 540)

H= 36000cal

H= 36kcal

Answer:

Water can become so heavily attracted to a different molecule, like salt (NaCl), that it can disrupt the attractive forces that hold the sodium and chloride in the salt molecule together and, thus, dissolve it.

Explanation:
The problem basically wants you to find a way to convert between the number of atoms present in the sample and the number of moles they are equivalent to.
To convert between atoms and moles we use something called Avogadro's constant, which basically acts as the definition of a mole.
More specifically, in order to have one mole of an element you need
6.022 x 10^23 atoms of that element. You can thus use this number as a conversion factor to take you from atoms to moles or vice versa.
In your case, you will have

3.90 x 10^ 26 atoms Zn x 1 mole Zn ( Avogrado’s constant) / 6.022 x 10^23 atoms Zn

= 6.5 x 10^8 is the answer

Answer:

Empirical formula: CO₂

Explanation:

The empirical formula is defined as the simplest ratio of atoms present in a molecule. We must convert the mass of carbon and oxygen to moles as follows:

Carbon -Molar mass: 12.01g/mol-

3.0g * (1mol / 12.01g) = 0.250 moles C

Oxygen -Molar mass: 16g/mol-

8.0g * (1mol / 16g) = 0.50 moles O

The ratio of O:C is:

0.50mol / 0.250mol = 2

That means the empirical formula is:

CO₂

Answer:

Explanation:

because when in molten form ions are Mobil (free) to move and can carry a charge however when in solid ions are fixed in position so they can't move and carry a charge.

Answer:

V = 0.24 L.

Explanation:

Hello there!

In this case, it is possible to approach this problem by using the ideal gas equation defined by:

[tex]PV=nRT[/tex]

Whereas our unknown is V, volume, and we solve for it as follows:

[tex]V=\frac{nRT}{P}[/tex]

Then since the STP conditions are ate 273.15 K and 1 atm, the volume of 0.011 moles of CO2 gas turns out to be:

[tex]V=\frac{0.011mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}\\\\V=0.24L[/tex]
