Answer:
4.14 x 10^24 molecules
Step-by-step explanation:
There are 6.95 x 6.022 x 10^23 or 4.14 x 10^24 molecules of Bal2 in 6.95 mol. This can be determined by using the Avogadro's number to calculate the number of molecules in a given amount of moles. Avogadro's number is equal to 6.022 x 10^23, which means that for every mole of a substance, there are 6.022 x 10^23 molecules of that substance. Therefore, 6.95 moles of Bal2 would contain 6.95 x 6.022 x 10^23 molecules, or 4.14 x 10^24 molecules.
