how will you prepare 0.38M sodium acetate solution
38 percent of 50 = 19

-38 degrees Fahrenheit is equivalent to -38 degrees Celsius.
Also 38. Centigrade is another name for Celsius.
38 degrees Celsius = 100.4 degrees Fahrenheit.
38° Bé Sodium Hydroxide NaOH SG = 145 / ( 145 - Bé ) = 145 / ( 145 - 38 ) = 145 / 107 = 1.355 If you look at the data of Sodium Hydroxide you will see that a S.G of 1.355 represents a concentration of approx. 33 % Weight

No, a 38% HCl solution is not the same as a 12N HCl solution. The concentration of a solution is based on the amount of solute dissolved in a specific volume of solvent. A 38% HCl solution means there is 38 grams of HCl in 100 mL of solution, while a 12N HCl solution means there are 12 moles of HCl in one liter of solution.
The solution to the factorization - the factors are 1, 2, 19, 38
The solution for x is 18.

A 38 out of 50 is a 76%. This is calculated by dividing 38 by 50 (38/50). You then multiply the result by 100, and the solution is your percentage out of 100.
I'm not certain what is meant by 38 HCl, but I suspect it must mean 38% HCl. Typically, concentrated Hydrochloric Acid is about 36-38%. 38% W/W means each 100 grams of 38% HCl contains 38 grams of dissolved hydrogen chloride gas. Generally, concentrated HCl is considered to by 12 Formal (or less correctly, 12 Molar) which is equivalent to 12 Normal. A close approximation of 0.5M would be as follows, using a Volume/Volume prep: Combine 11.5 parts water and add 0.5 parts 12 Molar HCl. For example: 115 mL of water plus 5 mL of 12 M HCl.
There are a total of 38 atoms in 2Na2SO4 (sodium sulfate). This includes 4 sodium atoms, 2 sulfur atoms, and 8 oxygen atoms.
x + 12 = 38. Subtract 12 from 38, getting 26. The 12 goes away because you subtracted it. x = 26, it cannot equal ten.
