To what volume (in milliliters) should you dilute 100.0 mL of a 5.50 M solution of CaCl2 solution to obtain a 0.950 M solution o
Alexxx [7]

Dilution law is given as:

M_{1}V_{1}=M_{2}V_{2}    (1)

where, M_{1} = molarity of initial concentrated solution.

V_{1} = volume of initial concentrated solution.

M_{2} = molarity of final diluted solution.

tex]V_{2}[/tex] = volume of final diluted solution.

Volume of initial concentrated solution of CaCl_{2}= 100.0 mL

Molarity of initial concentrated solution of CaCl_{2}= 5.50 M

Volume of final diluted solution of CaCl_{2} = 0.950 M

Put the values in formula (1),

5.50 M\times 100.0 mL=0.950 M\times V_{2}

V_{2} =\frac{5.50 M\times 100.0 mL}{0.950 M}

V_{2} =578.9 mL

Hence, final diluted volume of the solution is  578.9 mL.

I need help plzzz this is for today please help
aev [14]

Answer:

4. Water from upland areas often carries sediment and pollutants. The marshy land and plants in estuaries filter these pollutants out of the water. The plants in estuaries help prevent shoreline erosion. Estuaries also protect inland areas from flooding and storm surges.

5. Dredging impacts marine organisms negatively through entrainment, habitat degradation, noise, remobilization of contaminants, sedimentation, and increases in suspended sediment concentrations.

How does the vapor pressure of water at 10 c compare with its vapor pressure at 50 c?
Paha777 [63]
The vapor pressure of water at 50ºC will be greater than that at 10ºC because of the added energy and thus greater movement of the water molecules. If one knows the ∆Hvap at a given temperature, one can calculate the vapor pressure at another temperature. This uses the Clausius-Clapeyron (sp?) equation. It turns out the vapor pressure of water at 10º is 9.2 mm Hg, and that at 50º is 92.5 mm Hg.
