How many moles of KCL are contained in 0.538 L of a 2.3M KCL solution?
Since you have you're Molarity and your Liters you can use the formula M= mol/ L 2.3 M = mol / .538 L Multiply both sides by .538 to get the mol alone. mol of KCL = 1.2374
How many hydrogen atoms are in 1 kg?
Since we know the grams, 1kg or 1000g, we simply divide by the molar mass (1.0079g/mole) to get 992.2 moles of hydrogen. We then multiply by Avagadro's number, 6.0221415x1023. This gives us 5.975x1026 atoms in a 1kg sample of hydrogen.
How many helium atoms are there in a helium blimp containing 533 kg of helium?
To find the number of helium atoms in the blimp, you first calculate the number of moles of helium in 533 kg of helium using the molar mass of helium. Then, you use Avogadro's number (6.022 x 10^23) to convert moles to atoms. The final answer will give you the number of helium atoms in the blimp.
Is the mass number an average of the masses of all naturally occurring isotopes of an element?
No, it isn't. It is the atomic weight that is a weighted average of the mass of each of the naturally occurring isotopes of an element. The mass number, or A, is the number of protons and neutrons (the so-called nucleons) in the nucleus of an atom of an element. The atomic number, or Z, is the number of protons in the nucleus of an element.
How much energy is required to raise the temperature of 0.2 kg of aluminum from 15 and degC to 18 and degC (Refer to table of specific heat values.)?
538 J
Converting between moles of aluminum chloride and grams of aluminum chloride is most similar to what calculations?
Converting between moles of aluminum chloride and grams of aluminum chloride is most similar to converting between eggs and dozens of eggs. Just like one dozen equals 12 eggs, one mole of aluminum chloride contains Avogadro's number of particles (6.022 x 10^23) which corresponds to its molar mass in grams.
