Question
(A) A radioactive metal atom decays by emitting an alpha particle. The alpha particles are collected as an ideal gas. The volume of the gas collected was 12.05 mL at 765 mmHg and 23°C. How many atoms decayed during the period of the experiment?
(B) You vaporize a liquid substance at 100°C and 755 mmHg. The volume of 0.548 g of vapor is 237 mL. What is the molecular weight of the substance?
Summary
The question belongs to Chemical Engineering and it is about a radioactive metal atom decaying by emitting an alpha particle. The alpha particles are collected as an ideal gas. The question is how many atoms have decayed in this process. And the second question is about a liquid being vaporized. The molecular weight of the vapor is to be calculated.

Automata were definitely my problem area as far as computer science and programming assignments are concerned. However, after consulting the experts here everything was sorted out and my grades also improved. I will definitely thank the wonderful team of HwA to help me out during my crunch time.
1. Being a computer science engineer is my dream and it wouldn’t have possible for me to minutely understand the basics of C++ programming without the help of TheReliableTutor.com and the engineering assignment tutors. I grasped C programming on my own, but for C++ and Java, I am definitely grateful to TheReliableTutor
From the third semester of my computer science and engineering course I needed help with my programming homework. HwA came very handy at that point of time because they carefully understood the requirements and helped me get a good score.
I am extremely satisfied with the Visual C++ programming assignment help that I have received from HwA. The professor was very impressed with the quality of documentation and the grades speak for themselves.
I always found that circuit design assignments are very mind boggling and for that reason I often got low scores in the past. However, one senior of mine suggested that I take help from HwA as he got much benefit from them. I was a bit sceptical to be honest, at the beginning but eventually when I trusted them with one assignment, the feedback was brilliant. My grades spiked up and since then I take their help on a regular basis.

This solution is perfect ...thanks
Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
