Nickel with an average atomic mass of 58.65 amu has three isotopes. In the
lighter isotope, the difference in the
number of particles inside the nucleus
with each other is 2. The mass difference
between the other two isotopes is the size
of a neutron. The frequency of the heavier
isotope is 0.2% of the frequency of the
medium-mass isotope, and the difference
between neutrons and electrons is 7 in the
heavier isotope of nickel ion +2. What is
the percentage of lighter isotope
abundance?

Ibelieve it's celsius. hope this .

Contained in chromosomes which are located in the nucleus of the cell.

It decreases by 4 is your answer mark brainliest 

Use the universal gas law formula: pv = nrt now, the key word in this problem is stp, so at stp, temperature will always be 0 degrees celsius and pressure will always be 1.0 atm or 760 torr. given something is at stp, we already know the two variables pressure and temperature. the other thing we can find with the given information is moles. to find moles, just divide grams by molar mass of the element. 16.0g / 2(16.00)g/mol = 0.5 moles plug the values in to the equation pv = nrt (1.0 atm)( x ) = (0.5 )(0+273=273k) the r value is just a constant for when we use atm, liters, moles and kelvin. i'm assuming you want your answer in liters, but if you dont just move the decimal 3 to the right in your final answer. so when plugging these numbers in to your calculator and trying to find x, you get 11.20665 liters using significant figures the answer is 11.2 liters
