The STP is Standard temperature and pressure.
Standard temperature is defined as zero degrees Celsius (0° C)
Standard pressure supports 760 millimeters in a mercurial barometer (760 mmHg)
we have that
760 mmHg= 1 atm
therefore
the answer is 0 deg C and 1 atm.
The mole is simply an Avogadros number of anything( in this case Br atoms)
The Avogadro number is 6.022 x 10^23.
So no of moles = No of atoms / 6.022 x 10^23 = 2.03 x 10^24 / 6.022 x 10^23 = 3.37 Moles.
That's because <span>the specific heat capacity of water is higher than specific heat capacity of iron, meaning that the water would need to lose more heat energy to drop its temperature.</span>
