Together, a pure gold ring and a pure titanium ring have a mass of 16.00 g. both rings are heated to 80.0 °c and dropped into 14.1 ml of water at 22.6 °c. the water and the rings reach thermal equilibrium at a temperature of 28.0 °c. the density of water is 0.998 g/ml. the specific heat capacity of water is 4.18 jg·°c, the specific heat capacity of gold is 0.129 jg·°c, and the specific heat capacity of titanium is 0.544 jg·°c. calculate the mass of each ring.

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.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
