The molar mass of Cadmium is 112.41 grams, so first you need to convert your given value to moles. To do that divide 3 grams by the molar mass of 112.41 grams. That gives you an answer of .0267 moles of cadmium. Then to convert that value to atoms, you must use the constant of 6.022X10^23 atoms in one mole. Multiply the moles by that number, which will give you a final answer of (1.61X10^22) atoms in 3 grams of cadmium.

Hope this helps!

Based on the wintertime La Niña weather map, what do you think Florida's temperature and precipitation would be like during a wi
nika2105 [10]

Answer:

Temperature decreases and precipitation increases.

Explanation:

Temperature of Florida decreases and precipitation increases during a winter El Niño event. Due to El Niño event, precipitation occurs above average in Florida during Fall-Winter-Spring season. Storminess also increases during this El Niño event which increases the threat of severe weather in Florida during El Niño winters.

Radiation is spontaneously emitted from hydrogen-3 nuclei, but radiation is not spontaneously emitted from hydrogen-l nuclei or
miv72 [106K]

Answer : Option 1) nuclei of H^{1} and nuclei of H^{2} only.


Explanation : Radiation is spontaneously emitted from nuclei of H^{3} because this isotope of hydrogen is highly radioactive as compared to other isotopes of hydrogen namely; nuclei of H^{1} and nuclei of H^{2}.


They have much stable nucleus as compared to nuclei of H^{3}.


The more it is unstable the more radiations will be emitted from its nucleus.

Match.
Akimi4 [234]

Answer:

Molality, Solvent, Solute, Mole fraction, Molarity.

Explanation:

The expression of concentration that provides the moles of solute per kilograms of solvent is Molality.  This in the only expression referred to the solvent.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solvent is water.  When water is present, it is usually considered the solvent.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solute is sodium chloride.  There can be 1 or more solutes in a solution.

If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the Mole fraction of sodium chloride would be 0.25.  The mole fraction is equal to the moles of a substance divided by the total number of moles.

A way to express concentration that provides the moles of solute per liter of solution is Molarity.
