Answer:

the range should be 2.2 to 4.3

Explanation:

I think so because the numbers at the left side of the scale from 1 are more acidic so as it increases it's still acidic but lesser so 1 is more acidic than 2 so I used 2.2 as the beginning of the range because it's less acidic than A even though its a greater number and 4.3 is lesser than 4.4 but its still greater on the scale. frankly speaking I don't feel so correct because it's in decimal so try and compare facts thank you

Magnesium has three naturally occurring isotopes with masses of 23.99 amu, 24.99 amu, and 25.98 amu and natural abundances of 78
mihalych1998 [28]

Answer:24.31

Explanation:Contribution made by isotope of mass 23.99= 23.99×78.99=1894.97

Contribution made by isotope of mass 24.99=24.99×10.00=249.9

Contribution made by isotope of mass 25.98=25.98×11.01=286.04

Total contribution=1894.97+249.9+286.04=2430.91

Average mass=2430.91÷100

=24.31

Can someone help me solve this please 2.150 x 10 ^-12 dm / 5.02 x 10 ^-5dm^3
zavuch27 [327]

4.3 x 10⁻⁸dm⁻²

Explanation:

Problem:

                   \frac{2.150 x 10^{-12} dm }{5.02  x 10 ^{-5} dm^{3} }

 To solve this problem, we have apply the right rule of indices operation.

If we have an indices in the form;

 \frac{a^{n} }{b^{k} } = (\frac{a }{b } )^{n-k}

  Solving this problem:

   = \frac{2.15}{5.02}   x  10^{-12 -(-5})

   = 0.43 x 10⁻⁷

   = 4.3  x 10⁻¹ x 10⁻⁷

   = 4.3 x 10⁻⁸

for the units:

 \frac{dm}{dm^{3} }   = \frac{dm}{ dm x dm x dm} = \frac{1}{dm^{2} }  = dm^{-2}

  The solution is:  4.3 x 10⁻⁸dm⁻²
