Which solution is the most concentrated?

Chemistry

Answer:100 mL of 10 M NaCl, where NaCl has a molar mass of 58 g/mol

Explanation:

Concentration refers to the amount of substance in moles present in a solution. Number of moles is obtained from; number of moles= concentration*volume

For our chosen answer, 100/1000 * 10=1 mole. If we follow this procedure to calculate the amount of other solutions stated in the question, we will realize that 100ml of 10M NaCl has the highest number of moles present. Since concentration has to do with the number of moles present in a solution, this is the most concentrated solution.

Answer:

2.0 mL of 10.5 M H2O2, where H2O2 has a molar mass of 34 g/mol.

Explanation:

It is most concentrated because it contains 10.5 M of Hydrogen peroxide.

An ultraviolet ray of light has a wavelength of 1.5x10^-8 m. What is the ray's<br> frequency?
frutty [35]

Answer:

2 E16 Hz    or     2 * 10^16 Hz

Explanation:

The formula to determine frequency is f = c / λ.

f = frequency

c = speed of light

λ = wavelength

f = 3E8 / 1.5E-8

f = 2E16

This makes sense because UV light exists roughly

between 8E14 Hz and 3E16 Hz ----- 2E16 Hz falls in that range

What volume and mass of steam at 100 Celsius and 760. torr (or 1 atm) would release the same amount of energy as heat during con
erastova [34]
  
<span>As we know that
1 cu cm H2O = 1 mL H2O = 1g H2O 
now

Heat of fusion of water = 79.8 cal/g 
and

Heat of vaporization of water = 540 cal/g 

Atomic weight of water : H=1 O=16 H2O=18 
now by calculating and putting values

65.5gH2O x 79.8cal/gH2O x 1gH2O/540cal = 9.68g H2O (steam) 

9.68gH2O x 1molH2O/18gH2O x 22.4LH2O/1molH2O = 12.0 L H2O

John Dalton and Antoine Lavoisier were alchemists who tried to convert diamonds to gold.
larisa86 [58]
This is false. They were both chemists and they made many discoveries such as realizing that charcoal and diamond are different forms of the same element and proposing an atomic theory, but they never tried to turn diamonds to gold.
