Answer:

A. Students made a measurement error, because ending with more products is impossible.

Explanation:

The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction. If there is excess mass in the product, the students have made an error of some kind.

How many molecules of hypothetical substance b are produced when 29.9g of hypothetical substance a reacts? the molar mass of sub
Andrej [43]
<span>1.15x10^24 molecules of hypothetical substance b Making the assumption that each molecule in hypothetical substance a reacts to produce a single molecule of hypothetical substance b, then the number of molecules of substance b will be the number of moles of substance a multiplied by avogadro's number. So Moles hypothetical substance a = 29.9 g / 15.7 g/mol = 1.904458599 moles This means that we should also have 1.904458599 moles of hypothetical substance b. And to get the number of atoms, multiply by 6.0221409x10^23, so: 1.904458599 * 6.0221409x10^23 = 1.146892x10^24 molecules. Rounding to 3 significant figures gives 1.15x10^24</span>
