Answer 4

Upload the paper and here is the info I have
length of Mg ribbon 5.5cm
mass of 1 meter of Mg .75g
volume of H2 gas in tube 63.5mL
room temp 24C
barometric pressure 768mmHg
water vapor at room temp 22.4mmHg

Answer 5

part 2

Answer 6

Well for number 1 it is simple plug and chug.
.05/1=x/.75 solve for x. (watch sig figs)
63.5ml convert to liters .0635L*divide by 22.4 to get it to moles.
Pressure is just a subtraction.
And for the last one just convert it to moles and do the division. I can't help you too much with the second page :P

Answer 7

okay thank you~ Ive been out sick for awhile and i have to take a test on it tomorrow ugh

Answer 10

Answer 11

really, it just seems to small. Thank you!

Answer 12

Well typically in labs you use milliliters :P A mL is a one thousandth of a liter :P

Answer 13

on the next page it says to get your percent error, and typically gas volume should be 22.4L which is 1000 times small then what I got.

sorry about all the trouble
