Water at 23.5°c has a density of 0.99742 g/ml. a 10.5 ml sample of water at 23.5°c, delivered from a pipet had a mass of 10.4532 grams as measured on an analytical balance.
(1) show the calculation of the actual volume as determined from this mass.
(2) show the calculation of the % error in volume delivered for this pipet. % error = (%u2502calculated value - delivered value%u2502/ delivered value) x 100

To solve this problem it is necessary to apply the concepts related to density as a function of mass volume

Density can be expressed mathematically as:

Where,

m = mass

V=  Volume

Our values are given as,

m = 10.4532g

1) Then the value of the Volume is,

2) The error can be calculated from the calculated value and the delivered value,

Where,

Calculated value

Delivered value

Replacing with our values we have then:

the answer is false

explanation:

c)as speed changes, wavelength and frequency change.

everything changes!
