A Student measures the mass of a sample of a metallic element, M. Then the student heats the sample in or where it completely reacts to form the compound MO. The student measures the mass of the compound that was formed. Which of the following questions can be answered from the results of the experiment?

A) What is the density of M?

What is the molar mass of M?

C What is the melting point of M

What is the melting point of MO?

h let me think

i'm assuming that it's c.) red bank..

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.

the objects have the same charge is correct.
