Answer:
1720.8g water are necessaries
Explanation:
Mass percent is defined as the mass of solute (In this case, MgCl2) in 100g of solution (Mass MgCl2 + Mass water). To solve this question we must find the mass of solution that we need to produce th 1.5% by mass solution. Thus, we can find the mass of water that we need as follows:
<em>Mass solution:</em>
26.2g MgCl2 * (100g Solution / 1.5g MgCl2) = 1747g solution
<em>Mass water:</em>
1747g solution - 26.2g MgCl2 = 1720.8g water are necessaries
Fusion, fission, and radioactive decays of unstable nuclei, involve release or absorption of energy. The total number of neutrons plus protons does not change in any nuclear process. are not conserved, but the total number of protons plus neutrons is conserved.
The elements in each group have<span> the </span>same<span> number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (</span>group<span> one) </span>has<span> one electron in its outer shell.</span>
