To make 340mL of a 0.4 M solution of Lici, how many mL of a 8 M solution should be used?
ioda

Answer:

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

How much energy is required to raise the temperature of 10.6 grams of gaseous neon from
Alona [7]

Answer:

Approximately 1.95 \times 10^{2}\; \rm J.

Explanation:

Look up the specific heat of gaseous neon:

c = 1.03 \; \rm J \cdot g^{-1} \cdot K^{-1}.

Calculate the required temperature change:

\Delta T = (37.9 - 20.0)\; \rm K = 17.9\; \rm K.

Let m denote the mass of a sample of specific heat C. Energy required to raise the temperature of this sample by \Delta T:

Q = c \cdot m \cdot \Delta T.

For the neon gas in this question:

  • c = 1.03\; \rm J \cdot g^{-1}\cdot K^{-1}.
  • m = 10.6\; \rm g.
  • \Delta T = (37.9 - 20.0)\; \rm K = 17.9\; \rm K.

Calculate the energy associated with this temperature change:

\begin{aligned}Q &= c \cdot m \cdot \Delta T \\ &= 1.03\; \rm J \cdot g^{-1}\cdot K^{-1} \times 10.6\; \rm g \times 17.9\; \rm K \\ &\approx 1.95 \times 10^{2}\; \rm J\end{aligned}.

Where do surface waves occur
Verizon [17]

In physics, a surface wave can occur along any boundary of two different substances. The seismic type of surface wave happens at the boundary between air and rock—the surface of the earth.

Hope this helped you!

What is the molarity of a solution with 23 moles of solute, and 100 ml of a solvent?
Marina CMI [18]
Molarity is calculated by using following formula,

                            Molarity  =  Moles / Volume

Data Given:
                  Moles  =  23 moles

                  Volume  =  100 ml ÷ 1000  =  0.1 L

Putting values in eq. 1,

                              Molarity  =  23 mol / 0.1 L

                              Molarity  =  230 mol/dm³

Result:
           When 23 mol of solute is dissolved in a solvent to make a solution of 100 ml, then it will have a Molarity of 230 mol/dm³.
