ILKGA 2 years ago Find the molar mass of AgNO3 given the following atomic masses: AG = 107.9 u, N = 14.01 u, O = 16.00 u. Remember to round to proper significant figures

1. NotTim

What formula(s) relate to this question?

2. ILKGA

\[AgNO _{3}\]

3. NotTim

No, 'mathematical' formulas.

4. ILKGA

nope all the info I was given is in the question above

5. NotTim

You don't have a formula sheet? Or liek a textbook with the formulas?

6. ILKGA

What it has is an example problem but I don't see any formula. Do you want the example problem?

7. NotTim
8. NotTim

Something like that?

9. ILKGA

I don't have anything like that. O_o

10. NotTim

oh.

11. NotTim

Anyways, first add all the atomic masses together (do remember to multiply oxygen's atomic mass by 3 though, because there are 3 oxygen molecules in each AgNO3 molecule).

12. NotTim

Wait, is that all you do? I forgot.

13. ILKGA

so . 107.9 + 14.01 x 16.00(3) = 169.91

14. NotTim

you don't have to multiply the value of oxygen to the 'main body'. just multiply it by 3, then add it to the others.

15. ILKGA

that was supposed to be an addition sign sorry 107.9 + 14.01 + 48 = 169.91

16. NotTim

good enuff.

17. NotTim

We clear now? You know why the oxygen molecule was multiplied by 3?

18. ILKGA

yup

19. NotTim

awesome. SMOKEBOMB. POOf. NOTTIM AWAYYYY
