Butter has a specific gravity of 0.86. What is the mass of 2.45 L of butter?

Tema [17]

Answer:

mass of the butter is 2.107 kg

Explanation:

specific gravity = destiny of the substance / density of

the water at 4°C

0.86 = density of the butter / 1000

where density of the water is 1000 kg/m^3 at 4°C

density of the butter = 860kg/m^3

now,

density of the butter = mass of the butter / volume

860 = mass of the butter / 2.45 × 10^-3

( 1 L = 10^ -3 m^3)

mass of the butter = 2.107 kg

what is the relationship between the scale divisions marked on the graduated cylinders and the estimated uncertainty in the volu

AURORKA [14]

Answer:

The relationship between the scale divisions marked on the graduated cylinders and the estimated uncertainty in the volume measurements is that the larger the divisions the larger the uncertainty, and the smaller the divisions the smaller the uncertaintity.

Explanation:

In general, graduated cylinders are marked with divisions (lines) at equal spaces or intervals. There are divisions that show the measure with a number and a series of intermediate not numbered divisions in between two numbered lines.

The uncertainty of the instrument is determined as half the difference between two consecutive marks.

So, the larger the interval of two consecutive marks the larger the uncertainty.
