Answer:
<h2>136.2 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 425
density = 3.12 g/cm³
We have
Since cm³ = mL
We have the final answer as
<h3>136.2 mL</h3>
Hope this helps you
Answer:
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.
Explanation:
Americium has a molar mass of 243 g/mol.
There are 6.022*10^23 atoms in a mol (Avogadro's number).
6 atoms / 6.022 * 10^23 atoms/mol gives us:
9.963*10^-24 mols
Lastly: 9.963*10^-24 mols * 243 g/mol = 2.42*10^-21 g
<span>If you placed the letter g under a microscope, the image in the field would look completely inverted. So, instead of seeing a regular letter g, it would be inverted both from up to down and from left to right, so when you look at the letter under a microscope, it would no longer look like the letter g, but rather like the number 6. This would happen because of the convex lens which tends to invert, or flip images.</span>
