Blood disease, any disease of the blood, involving the red blood cells (erythrocytes), white blood cells (leukocytes), or platelets (thrombocytes) or the tissues in which these elements are formed-the bone marrow, lymph nodes, and spleen-or of bleeding and blood clotting.
Those were the notes my teacher gave me. Hope that helps!! : )
2.3g of sodium would be needed to create a 100 millimole concentration in one liter.
Given,
Mole of Na+ = 100 millimole
As we know that,
1 millimole = 10 -³ mole
Mole of Na+ in 100 millimoles = 100 × 10 -³ mole
= 0.1mole
<h3>What is Mole? </h3>
Mole is defined as the ratio of mass of Na+ to the molar mass of sodium.
<h3>What is Molar Mass? </h3>
The molar mass is defined as the sum of the total mass in grams unit of the atoms present to make a molecule per mole.
Mole of Na+ = mass of Na + / molar mass of Na +
0.1 = mass of Na + / 22.99 gl mol
Mass of Na + = 0.1 × 22.99
= 2.299 g
Mass of Na + = 2.3 g
Thus, we calculated that 2.3g of sodium would be needed to create a 100 millimole concentration in one liter.

Thank you so much if that helps you!!!!
This problem is providing information about a reaction between magnesium and hydrochloric acid. However, the moles of the latter are required given 50 cm³ of a 0.2-M solution, making this problem more about the application of molarity. At the end, the answer turns out to be 0.01 mol.
<h3>Molarity:</h3>
In chemistry, we use units of concentration in order to represent the relative amounts of solute and solvent in a solution. More specifically, molarity relates the moles of the solute with the liters of solution according to:
Thus, since this problem asks for the moles of hydrochloric acid in 50 cm³ of a 0.2-M solution, we must first calculate the volume in liters with:
To finally solve for n, moles, to obtain:
