47 In a titration, 20.0 milliliters of a 0.150 M NaOH(aq) solution exactly neutralizes 24.0 milliliters of an HCl(aq) solution.

What is the concentration of the HCl(aq) solution?(1) 0.125 M (3) 0.250 M
(2) 0.180 M (4) 0.360 M

The answer is (1) 0.125 M. The reaction equation is NaOH + HCl = NaCl + H2O. So the mol number of NaOH and HCl is the same. So suppose the concentration of HCl is x, we can have equation: 20*1.15=24*x. So x= 0.125 M. (M means mol/L, but if we use the same unit at both side of the equation, it is ok.)

Which statement describes the relationship between the scientific method in the scientific process
Oksana_A [137]

Answer: The methodology is the science that addresses these issues.

Explanation:

There are several steps to exploring to obtain valid scientific results. The scientific method is one of those elements. The scientific method involves specific steps that need to be taken to begin the scientific process adequately. By the scientific method, we also mean the hypothesis or assumption that needs to be put in the paper to try to defend it later and in fact. By scientific process, we suggest the following steps we take after evaluating a hypothesis. The scientific method is the very making of a particular scientific work, that is, its central part.

What is the molarity of a 1.44 (m/v)% solution of an HCOOOH (Formic acid)?
AlexFokin [52]

This problem is providing the mass-volume percent of a formic acid solution so its molarity is required and found to be 0.313 M after the following calculations.

<h3>Molarity</h3>

In chemistry, units of concentration provide a measurable understanding of the relationship between the relative amounts of both solute and solvent. In the case of molarity, one must relate moles of solute and liters of solution as follows:

M=\frac{mol\ solute}{Volume\ solution \ in \ L}

In such a way, when given this mass-volume percent of 1.44% for the formic acid in the solution, one can assume there is 100 mL of solution and 1.44 g of solute (formic acid), which means one must convert the volume to liters and the mass to moles with:

mol\ solute=\frac{1.44g}{46.03g/mol} =0.0313mol\\\\Volume\ in \liters: 100mL*\frac{1L}{1000mL}=0.100L

Finally, we plug in these numbers in the equation for the calculation of molarity:

M=\frac{0.0313mol}{0.100L}\\\\M=0.313M
