Question

help! question for you guys :)

6. Calculate the mass of 10ml of water in the graduated cylinder using 14.54 for volume and the density of water of 1.00 g/mL. Calculate the mass of the water using the formula for density:

Density = mass
volume

Answer 1

so the volume of the water in the cylinder is 10 mL or is it 14.54 mL ?

Answer 2

volume is 14.54

Answer 3

ok so

Density = Mass/Volume

D = m/v

1 = m/14.54

1*14.54 = m

14.54 = m

m = 14.54

Answer 4

so the mass is 14.54 grams

Answer 5

oh brilliant thanks so much for explaining that!

Answer 6

you're welcome

Answer 7

quick question, if the density of the water is 1g/mL would i be multiplying 14.54 times 10 and not 1??

Answer 8

mass = (Density)*(Volume)

mass = (1 g/mL)*(14.54 mL)

mass = 14.54 grams

Answer 9

notice how the mL units match and cancel out

Answer 10

this is of course assuming the given volume is 14.54 mL and not 10 mL

Answer 11

ya i am using the volume from the previous problem (as instruscted to). . . just curious as to why the 1g/mL was being mentioned. . .

Answer 12

that's the density of water

basically it tells you how packed water is

Answer 13

or it tells you how much mass is in one unit of volume

Answer 14

ohhh ok gotcha :)
