The boiling point of a substance is tested. After 10 tests, the result is given as 37+/−3°C. Which conclusion can be drawn from

this result? (1 point)
The scientists do not need to collect more data because they have narrowed down the range of the results.

The scientists should not report these results until they have the exact number.

The actual boiling point is either 34°C or 40°C.

The actual boiling point is probably between 34°C and 40°C.

Question 4 (1 point)<br> If you have exactly one million atoms how many moles do you have?
rjkz [21]

Answer:

                       1.66 × 10⁻¹⁸  Moles

Explanation:

                     As we know one mole of any substance contains 6.022 × 10²³ particles (atoms, ions, molecules or formula units). This number is also called as Avogadro's Number.

The relation between Moles, Number of Atoms and Avogadro's Number is given as,

             Number of Moles  =  Number of Atoms ÷ 6.022 × 10²³ Atoms/mol

Putting values,

              Number of Moles  =  1.0 × 10⁶ Atoms ÷ 6.022 × 10²³ Atoms/mol

              Number of Moles  =  1.66 × 10⁻¹⁸  Moles

The table below shows the number of sub-atomic particles in an atom of sodium. Sub-atomic Particles Sub-atomic Particle Number P
AlexFokin [52]

Answer is: the amu of a sodium atom is 23.

The unified atomic mass unit (amu) is a standard unit of atom mass.

One unified atomic mass unit is approximately the mass of one nucleon (proton or neutron).

The unified atomic mass unit is equal 1.66·10⁻²⁷ kg.

n(p⁺) = 11; number of protons in sodium atom.

n(n°) = 12; number of neutrons of sodium atom.

n(p⁺ + n°) = 11 + 12.

n(p⁺ + n°) = 23; number of nucleons in sodium atom.
