Final Answer:
There are 119 grams in 6.18×10^22 molecules of N2O3 (Option B).
Step-by-step explanation:
To find the grams of N2O3, you need to use the molar mass and Avogadro's number. The molar mass of N2O3 is calculated by adding the atomic masses of nitrogen (N) and oxygen (O). Once the molar mass is determined, you can use Avogadro's number to convert from moles to molecules. The given quantity (6.18×10^22 molecules) is first converted to moles using Avogadro's number. Then, the moles are converted to grams using the molar mass of N2O3. The calculated value is 119 grams.
Option B is the answer.
