An element can be represented symbolically in terms of its atomic number and mass number as:
_{Z}^{A}\textrm{X}
where X = symbol of the element
A = atomic mass
Z = atomic number
In this case we have the representation as:
_{0}^{1}\textrm{n}
where n = symbol for neutron
mass number of neutron = 1
charge/atomic number of neutron = 0
Ans: D) A neutron of zero charge and one unit mass
34 is the answer i htink sorry if its wrong
It has a higher boiling point and a lower freezing point
In order to compute the mass of each solute in the sample, we simply multiply the percentage mass of each solute with the total mass of the solution. This is ad such:
Mass (NaCl) = 0.0486 x 294
Mass (NaCl) = 14.29 grams
Mass(Na₂CO₃) = 0.0754 x 294
Mass(Na₂CO₃) = 22.17 grams
