Is My Calculation of NO2 Production Accurate?

In summary, when solving a chemistry homework problem, it is important to read and understand the problem, identify the given information and what you are trying to solve for, choose the appropriate formula or equation, substitute the given values, solve for the unknown variable, and check your answer for reasonableness. Units are also crucial and should be carefully considered based on the given information. If you get a different answer from the back of the textbook, it is important to double-check your work and ask for help if needed. To improve problem-solving skills, practice and break down problems into smaller parts. Common mistakes to avoid include not reading the problem carefully, using the wrong formula, forgetting to convert units, making calculation errors, and not checking the answer for

2N2O5 heat-- 4NO2 + O2

1.618 g of O2 are produced, how much NO2 in grams are produced? I got 9.30 g NO2, is that right? I used 1 mol O2 = 32 g O2, and 1 mol NO2 = 46g NO2. I first converted g O2 to Mol O2 then used the balanced equation to convert from mol O2 to mol NO2, then converted to NO2 to grams. If anyone can tell me if I did this right I would greatly appreciate it.

The steps that you outlined are good, however I haven't checked your calculations specifically.

Based on your calculations, it seems like you have correctly converted the given amount of O2 to moles and then used the balanced equation to determine the moles of NO2 produced. Your final step of converting moles to grams using the molar mass of NO2 is also correct. Therefore, your answer of 9.30 g NO2 appears to be correct. However, it is always a good idea to double-check your work and make sure you have used the correct molar masses and performed the conversions accurately. Overall, it seems like you have a good understanding of the concept and have solved the problem correctly.
