A flexible weather balloon contains helium gas at a volume of 855 L. Initially, the balloon is at sea level, where the temperatu

re is 25oC and the barometric pressure is 0.947 atm. The balloon then rises to an altitude of 5500 ft, where the pressure is 0.783 atm and the temperature is 15oC. What is the change in the volume of the balloon as it ascends from sea level to 5500?

Hydrogen has three naturally occurring isotopes which figure into the average atomic mass found on the periodic table (1.00974):
Art [367]
The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes. 

Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.

You need to use a dilute hydrochloric acid solution in an experiment. However, the only bottle of hydrochloric acid in your lab’
mr_godi [17]

The pH of the diluted HCl solution is 1.3.

Explanation:

Given:

The concentrated HCl solution of 8.0 M. The 1.5 mL of 8.0 M HCl is diluted with water to 250 mL volume.

To find:

The pH of the diluted HCl solution.

Solution

  • The concentration of the HCl solution before dilution = M_1=8.0 M
  • The volume of the HCl solution taken for dilution = V_1=1.5 ml
  • The concentration of the HCl solution after dilution =M_2=?
  • The volume of the HCl solution after dilution = V_2=250 mL

Using the Dilution equation:

M_1V_1=M_2V_2\\8.0M\times 1.5ml=M_2\times 250 mL\\M_2=\frac{8.0M\times 1.5ml}{250 mL}=0.048 M

The concentration of diluted HCl solution = 0.048 M

HCl(aq)\rightarrow H^+(aq)+Cl^-(aq)

In the 1 M solution of HCl, there are 1 M of hydrogen ion, then the concentration of hydrogen ions in 0.048 M of HCl will be:

[H^+]=1\times 0.048M=0.048 M

The pH of the diluted HCl solution :

pH=-\log [H^+]\\=-\log [0.048M]=1.18 \approx 1.3

The pH of the diluted HCl solution is 1.3.
