Answer:

32.057 amu

Explanation:

\text{Average atomic mass = Mass}\times \text{abundances}

M=95\%\ \text{of}\ 31.972 +0.76\%\ \text{of}\ 32.971 +4.22\%\ \text{of}\ 33.967 \\\\M=\dfrac{95}{100}\times  31.972 +\dfrac{0.76}{100}\ \times \ 32.971 +\dfrac{4.22}{100} \times \ 33.967\\\\M=32.057\ \text{amu}

So, the average atomic mass of sulfur is 32.057 amu.

A chemical equation that does not indicate relative amounts of reactants and products is called
Zielflug [23.3K]

Answer:

The correct answer is skeleton equation.

Explanation:

In chemistry, the skeletal formula of a compound is an abbreviated representation of its molecular structure. Skeleton formulas are used because they clearly show complicated structures, they are fast and simple to draw.

All atoms that are not carbon or hydrogen are represented by their chemical symbol. The relative amounts of reagents and products are not indicated.

Have a nice day!

Answer:

the proton and the neutron

Explanation:

mass of The proton is approximately  1.6726 × 10^-27 Kg

mass of the electron  is approximately 9.109 × 10^-31 Kg

mass of the neutron  is approximately 1.6749 × 10^-27 Kg

Here we see that mass of proton and neutron is approximately similar.

_____________________________________________

Lets see what is  the mass of these particle IN atm unit

mass of these particles can also be described in form of amu(atomic mass unit)

1 atm is the mass defined as 1/12 th of mass of the carbon-12(c-12) atom.

In terms of unit atm

mass of proton = 1 amu

mass of electron = 5.45 × 10−4 amu

mass of neutron = 1 amu

hence we can say that mass of proton = mass of neutron.

mass of atom is sum of mass of all the neutron and proton in the atom.

Hence, mass of neturon and atom cannot be equal.

This makes option four the neutron and the atom , the wrong choice.

correct answer is the proton and the neutron

therefore, An atom contains one proton , one electron and one neutron then, mass of proton is similar in mass of neutron.
