Where is the mass of an atom found
Virty [35]

Answer:

The mass of an atom is found in its nucleus.

Explanation:

An atom is made of three different particles: protons, neutrons and electrons.

Protons (positive charge) and neutrons (no charge) each have a mass of 1 AMU. They are both found in the nucleus (centre) of the atom.

Electrons (negative charge) are considered to have a mass of 0. Their mass is not actually 0, but very close so we do not count them. They are not in the nucleus, but found in shells surrounding the atom.

To calculate the mass of an atom, we add the number of protons and the number of electrons.

m = P + N

What is the freezing point of an aqueous solution that boils at 103.7 degrees Celsius?
inna [77]
For this, we use equations from the colligative properties of solutions specifically boiling point elevation and freezing point depression. The equations for these are expressed as:

ΔTb = kb m

where k is a boiling point elevation constant and m is the concentration in terms of molality

ΔTf = kf m 

where k is a freezing point elevation <span>constant and m is the concentration in terms of molality
</span>
We use both expression to solve for the freezing point. For this case, concentration is the same. The equation will then be:

ΔTf = kf ( ΔTb / kb )
0-Tf = 1.86 (103.7 - 100 / 0.512 )
Tf = -13.4°C

A sample of pure iron has a mass of 5.00g. What's the calculation of its volume??? Please help me or my moms gonna freak
GarryVolchara [31]
Since the iron is pure, we can look up its density value online and will always be true. This density value of iron is 7.87g/L. Now, we can use the density formula (D = m/V) and rearrange it to solve for V. This new equation is then V = m/D. Next, we plug in our known values and solve for V (5.00g/7.87g/L). This gives us our final answer of 0.635L (three sig figs due to the three sig figs in the provided mass).

Hope this helps!

Is matter continuous and therefore has no finer structure or is it discontinuous and thus made or tiny particles
Marta_Voda [28]

Matter is discontinuous, and it is made of tiny particles called atoms

Explanation:

Matter is not a continuous structure, but it consists of tiny particles called atoms.

An atom consists of three types of particles:

  • Proton: the proton is in the nucleus of the atom. it has a positive electric charge of +1.6\cdot 10^{-19}C (also called fundamental charge). Its mass is 1.67\cdot 10^{-27}kg.
  • Neutron: the neutron is also in the nucleus of the atom, but it has no electric charge. Its mass is similar to the mass of the proton (slightly heavier). Neutrons and protons are held together in the nucleus through the strong nuclear force.
  • Electron: electrons are found in a "cloud" outside the nucleus. Electron has negative electric charge equal to -1.6\cdot 10^{-19}C. Its mass is much approximately 1800 times smaller than that of the proton, so it is considered as negligible.
