B. concentrated
A. is incorrect because it COULD be saturated. C. is incorrect because a large amount of salt is concentrated into a small amount of water, so it can't be diluted, relatively. D. is incorrect because it does not describe a solution's molality or molarity.
Divide by the atomic mass of iron. Look at your periodic table.
<span>About 11 moles. 1 mole of iron contains 6.022 * 10^23 atoms of iron.</span>
Medical Uses. Pharmacists use titration to achieve a desired mix of compound drugs.
Answer: 0.714 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of stock solution = 1.00 M
= volume of stock solution = 1.00 L
= molarity of dilute solution = ?
= volume of dilute solution = (1.00+0.40) L = 1.40 L
The concentration of a 1.00 M solution of sodium chloride (NaCl) after exactly one liter of the solution is mixed with 0.40 L of water is 0.714 M
Chemical reaction: 2A + B → unkwown product.
Molecularity<span> is the number of molecules that come together to react in an </span>elementary (single-step) reaction and Molecularity<span> in </span>chemistry<span> is the number of molecules that come together to react in an </span>elementary (single-step) reaction <span>and is equal to the sum of </span>stoichiometric coefficients<span> of reactants in this elementary reaction.
