Answer:
+2.5
Explanation:
So the oxidation number of S in Na2S4O6is +2.5.
Pv=nRT
where,p=199, R(constant)=8.314, V=4.67 T=30C=293K
n=pv/RT=0.38 moles
274 mL H3 O+ and fully neutralized
It will take one teaspoon of Mg(OH)2 to completely neutralize 2.00×10^2mL of H3O+.

the question you are looking for is
People often take milk of magnesia to reduce the discomfort associated with acid stomach or heartburn. The recommended dose is 1 teaspoon, which contains 4.00x 10^{2} mg of Mg(OH)_2. What volume of an HCl solution with a pH of 1.3 can be neutralized by one dose of milk of magnesia? If the stomach contains 2.00x10^{2}mL of pH 1.3 solution, is all the acid neutralized? If not, what fraction is neutralized?
A 0.50-quart jar contains 2.0 pounds of honey. 1.9 g/ml is the density of the honey.
Density is a measure of how much "stuff" is in a given space. For example, a block of the heavy element lead (Pb) is denser than the softer, lighter element gold (Au). Styrofoam blocks are less dense than bricks. Defined as mass per unit volume.
The density of an object is one of the most important and easiest physical properties to measure. Density is commonly used to identify pure substances and to characterize and estimate the composition of various types of mixtures. Density is an important concept because it can determine which substances float and which sink when placed in a liquid. In general, matter floats as long as its density is less than that of the liquid.
