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?
1 mole of helium (or 4 g or 0.004 kg) has 6 x 1023 atoms. So, 536 kg of helium will have 8.04 x 1028 atoms
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.
