## anonymous one year ago This exercise requires you to enter a mathematical expression. Solve for P. pv/v=nRT/v

• This Question is Open
1. Nnesha

$\huge\rm \frac{ pv }{ v }=\frac{ NRT }{ v }$ and you don't need a calculator

2. Nnesha

pv over v = ?

3. anonymous

the thing is i dont get it

4. Nnesha

you have to solve that equation for *P* so our job is to cancel out v from left side to do that we need to divide both sides by v

5. Nnesha

pv/v = ? 2/2= 1 so pv/v = ?

6. Nnesha

p is multiplying with v that's we are dividing (opposite of multiplication ) to cancel out v from left side

7. anonymous

does the p by itself?

8. anonymous

hello

9. anonymous

Do you still not understand?

10. anonymous

no

11. Nnesha

yes so when you divide pv/v $\frac{ p\cancel{v} }{\cancel{ v} }= p$

12. anonymous

k then what

13. anonymous

Ok so you understand why she had pv/v=nrt/v

14. anonymous

i knew that i p is by it self .and i dont know want to do next

15. Nnesha

then nothing you need p itself and you got that.

16. Nnesha

that's it!

17. Nnesha

and i also mentioned why we dividing by v

18. anonymous

i dont put nRt/v

19. Nnesha

what do you mean ?

20. anonymous

that is put of the question

21. anonymous

It's not going to be a number answer

22. anonymous

i know

23. Nnesha

so P = nrt/v

24. Nnesha

isn't it right ?

25. anonymous

That's what I got

26. anonymous

27. Nnesha

enter where ? and that's not up there ^^ your question is **This exercise requires you to enter a mathematical expression. Solve for P. pv/v=nRT/v ***

28. anonymous

so what is the right answer

29. anonymous

hello

30. Nnesha

what did you get after dividing both sides by v ?

31. anonymous

nothing it told it was wrong

32. Nnesha

subject name ? what's the statement ?

33. Nnesha

i guess they are asking totally different thing .....

34. anonymous

You can also enter your answer directly instead of using the palette. Try typing 'nRT/V' in the answer box. Notice how the expression is displayed in the answer box as you enter it. Some questions will display additional instruction on how your answer should be entered. Here instructions might be added if you need to substitute numeric values for R or which variables should only be entered in the answer box.

35. anonymous

it goes with pv/v=nRT/v

36. Nnesha

It's $\huge\rm 'Pv=nRT'$ should mentioned that *'* anyway i was doing algebra stuff

37. Nnesha

and i'm sorry i don't know how to solve that for P

Were you given values for n, T, and V?
