In the laboratory, a group of students was assigned to determine the density of an unknown liquid. they used a buret to find a volume of 2.04 ml. the mass was determined on an analytical balance to be 2.260 g. how should they report the density of the liquid?

They should report the density as 1.11 g/L .

Density = mass/volume = 2.260g/2.04 mL

My calculator says the density 1.107 843 137 g/mL

However, the answer can have no more significant figures than are in the number with the fewest significant figures.

The volume measurement has only three significant figures, so we must round off the density to three significant figures.

We drop all the digits after the zero.

The digit to be dropped is 7, so we round up the last significant figure of the answer.

1.107 843 137 → 1.11

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
