Cm^3=1cm*1cm*1cm
=10mm*10mm*10mm
=1000 mm^3
Answer:
8×10^(-3) mol/L
Explanation:
The formula for finding the hydrogen ion concentration is...
[H⁺] = 10^-ph
[H⁺] = 10^(-2.1)
[H⁺] = 0.00794...mol/L = 8×10^(-3) mol/L
The answer is to 1 significant digit because the pH has one decimal place.
Answer:
1/16 is the answer.........
Hydrogen and helium because they only have one electron shell and it only holds up to two electrons in it.

Answer:</h3>
D. Multiply the atomic mass of fluorine by 1.25
<h3>
Explanation:</h3>
<u>We are given;</u>
We need to identify the formula that shows the equivalent in mass
- We need to know the relationship between mass of an element, its atomic mass and the number of moles;
- That is; Number of moles = Mass of the element ÷ Atomic mass
Therefore;
Mass of the element = Number of moles × atomic mass
- Thus, in this case, to get mass we will multiply number of moles by atomic mass of Fluorine.
- That is, multiply atomic mass of fluorine by 1.25 moles .
