Answer:

No of neutrons and protons decides mass of the atom. Electrons having negligible

mass are ignored.

Mass of atom

Mass of atom= sum of no of protons(Z) and neutons(N)

=Z+N

For eg:

In hydrogen atom,

Mass of H= Z+N

=1+0

=1 AMU

Where is the magnetic field of a bar magnet the strongest?

Alla [95]

The correct answer is A. The magnetic field is strongest at the north pole and the south pole of a bar magnet. At the poles, the magnetic field is equally strong while the force is weaker at the middle of the bar. The field lines are closely packed at each pole and it gets wider as the lines get further from the pole.

What is the concentration of HNO3 if 5.00×10−2 mol are present in 905 mL of the solution?

Zepler [3.9K]

Answer:

0.05525 M or 55.25 mM

Explanation:

Concentration = moles/volume

*Note that volume is expressed in L so you will need to convert mL > L here

$C= \frac{n}{V}\\C= \frac{0.05}{0.905}\\C=0.05525$
