How many molecules are present in 1.5 moles of NaCl?
6.02x1023
9.03x1023
To determine the number of molecules present in a given amount of a substance, you can use Avogadro's number, which represents the number of particles (atoms, molecules, or ions) in one mole of a substance. Avogadro's number is approximately 6.022 x 10^23 particles per mole.
In this case, we want to find the number of molecules in 1.5 moles of NaCl. Since NaCl is a compound consisting of ions, we can convert the number of moles to molecules using the ratio of Avogadro's number.
1 mole of any substance contains 6.022 x 10^23 particles, so 1 mole of NaCl contains 6.022 x 10^23 molecules of NaCl. Therefore, to find the number of molecules in 1.5 moles of NaCl, we can use the following calculation:
Number of molecules = (1.5 moles) x (6.022 x 10^23 molecules/mole)
Calculating this equation gives us:
Number of molecules = 9.033 x 10^23 molecules
Therefore, there are approximately 9.033 x 10^23 molecules in 1.5 moles of NaCl.
