<span>the answer is 7...What is the mass number of the isotope lithium-7?
the mass of isotope lithium-7 is 7. </span>
The colour of the star and the brightness.
I’m slightly confused about the wording of the question but if both the same y-intercept that means both company’s have the same flat rate charge for artwork.
We know avogadro's number = 6.023 x 10²³
1 amu = 1 atomic mass unit = 1/ (6.023 x 10²³) gm = 1.66 x 10⁻²⁴grams
<span>Now, to convert amu to grams,
131.29 amu = 131.29 x 1.66 x 10</span>⁻²⁴grams
<span>= 2.18 x 10</span>⁻²²<span> grams is the answer</span>
