Explanation:
Fundamentally the aluminum foil is a rectangular prism. It has a length, a width, and a thickness.
The volume of a rectangular prism is expressed as
If we know the volume and two of the three dimensions, we can rearrange the equation to solve for the thickness.
But we should also be sure to confirm our units.
A liter is defined as 1000 cm^3. Therefore a mL is equal to 1 cm^3.
You should convert the units of measure given in the problem statement such that the units are aligned. For example, 10.0mm will be 1 cm and 12.5m will be 1250 cm. This will give you a height in cm.
Answer:
Explanation:
Hello,
In this case, for the given chemical reaction, we first identify the limiting reactant by noticing that due to the 1:1 mole ratio for magnesium to iodine the reacting moles must the same, nevertheless, there are only 2.68 moles of magnesium versus 3.56 moles of iodine, for that reason, magnesium is the limiting reactant, so the theoretical turns out:
Thus, we compute the percent yield as:
