Answer 1

I would have to say the best dream job to meet both your requirements would be working at a client overseas as anurse

Answer 2

like being in the army

Answer 3

YES YOU DONT HAVE TO BE ACTIVE BUT YOU CAN BE RESERVES AND STILL DO WHAT YOU LIKE

Answer 4

well i'am kind of think about doing that... But still want more options

Answer 5

why are you asking this in the chemistry section? do you want a job in a chemistry related field?

Answer 6

okay ,What is the density of a sample that has a mass of 77.0g and a volume of 36mL???

Answer 7

\(\rho=\dfrac{m}{V}=\dfrac{77.0g}{36mL}\)

Answer 8

what does the P stand for and is m= mass and V= volume??

Answer 9

rho "\(\rho\)" is density

yes for the rest

Answer 10

Will a sample float in water that has a mass of 64g and a volume of 66mL??? can you tell me in step by step of how your doing it????

Answer 11

find the density, if it's denser than water it won't float (density of water 1 g/mL)

Answer 12

Would you use the formule you did like m over v.. on how you got 1g/mL

Answer 13

Find the mass of a 27.9mL sample of ice, which has a density of 0.917g/mL

Answer 14

yep, same formula for both (the density of water is a very common value, I've memorized)

Answer 15

okay can you answer the other question i posted

Answer 16

Find the mass of a 27.9mL sample of ice, which has a density of 0.917g/mL

Answer 17

you're using the same formula, but instead solving for mass

Answer 18

but you divide the 27.9mL to the density which is 0.917g/mL = 0.33

Answer 19

do you know how to solve algebraic problems?

like \(2=\dfrac{x}{3}\) ?

Answer 20

yes

Answer 21

you need to do the same here

Answer 22

multiple

Answer 23

yup

Answer 24

the numbers instead of dividing

Answer 25

okay thanks your very helpful

Answer 26

one more question

Answer 27

will a sample float in water that has a mass of 42.7g and a volume of 21.13mL?

Answer 28

same thing, find the density, if it's denser than water it won't float

Answer 29

what do you mean denser than water it wont float

Answer 30

i got 2.021g/mL

Answer 31

got the density

Answer 32

seems right

Answer 33

if the density of the object is greater than water's density (and by that i mean if the density is greater than 1 g/mL) the object won't float.

Answer 34

ohhhhh Okay thanks.

Answer 35

no problem

Answer 36

are you a teacher

Answer 37

nope. i'm a student myself

Answer 38

what grade i'm a junior

Answer 39

and have a bad grade in chemistry...

Answer 40

i'm in university

Answer 41

we'll you've come to the right place. if you're willing to do some work, there are a lot of people here that can help you raise that mark.

Answer 42

ohh, well that's great.. When i need help with chemistry again i'll need your help. You actually teach better than my science teacher..

Answer 43

he didn't even teach us what formula to use to find the density...

Answer 44

lol people say that. It's unfortunate that the people teaching the material are, well, not good at it. It alienates the students from it. My high school chem teacher was awesome.

Answer 45

lol how were supposed to solve it then? ridiculous

Answer 46

right... I search every where and found this website

Answer 47

thanks

Answer 48

bye now

Answer 49

no problem, see ya
