How is Oxygen -18 different from oxygen -16?
Oksanka [162]

A  O-18 has 2 more neutrons than O-16

<h3>Further explanation</h3>

Oxygen is located in group 16 in the p block which has the atomic number 8

In the atomic symbol (neutral), the atomic number indicates the number of electrons and protons. while the number of neutrons is obtained from the difference between the mass number and the atomic number.

The isotope will have the same number of protons (atomic number) but a different mass number

Isotopes of oxygen include: O-18 and O-16

\tt _8^{18}O~\rightarrow neutron=18-8=10,proton=8\\\\_8^{16}O\rightarrow neutron=16-8=8,proton=8

What is the density of a substance that contains 850 milligrams for every mL? Express your answer in grams per cm³.
Temka [501]

The density  of substance that contain  850 milligrams  for every  Ml  is  

0.85 g/Cm³


    calculation

<em>  </em><em>step 1:</em><em>convert   850 Mg  to g</em>

<em>that is 1  mg=0.001 g</em>

<em>         850 mg =? g</em>

<em>= (850 mg   x  0.001  g)/ 1 mg=0.85 g</em>


<em>step 2:  convert  Ml  to  Cm³</em>

<em>            that is 1  Ml =  1 cm³</em>


<em>therefore density  =</em><em> 0.85 g/Cm³</em>
