Why is barium sulfate good shield against gamma rays?
Barium Sulfate is used as a radio contrast agent for radio imaging. Radio Contrast agents are those agents which improve the visibility of body parts in the process of X RAY. Barium is a heavy metal with a high atomic number of 56. Thus it absorbs radiations such as X Rays or Gamma Rays better than other metals thus preventing the radiation exposure to our body. Thus it is used as a shield against gamma rays.
How do you convert parts per million to a percentage?
parts per million to percentage divide by 10 000 percentage to parts per million mulyiply by 10 000 Dachu
How do I convert 10 percent CO2 to parts per million CO2?
-- Take the number of percent. -- Multiply it by 10,000-- The answer is the number of parts per million. . 10 percent = 100,000 parts per million.
What does 1000 ppm mean?
PPM is an abbreviation for parts per million. If you have 1000ppm, then you have 1000 parts "A" per every million parts of your mixture. Therefore, the substance you are measuring is .1% part "A."
What does good solubility mean?
Solubility is when a soluble can dissolve in a solvent. Soluble=what is dissolved Solvent=what dissolves the solute. These are the parts of a solution. Think of sugar and water. pour the sugar into the water. After some time the sugar will have seemed to disappear. It hasn't but it did dissolve. That means it has good solubility. Now think of a piece of plastic in water. No matter how long the plastic stays in the water, it will not dissolve.
What percent of the element barium found on earth?
The abundance of barium is 456 parts per million (numbers of atoms). That is 0.05 per cent, approx.

How do you compare solubility between substances?
Solubility can be written as %m/m (mass in g per 100g), %m/v (mass in g per 100mL), %v/v (mL per 100mL), ppm (parts per million), ppb (parts per billion) etc. Solubility is also dependant on pressure and temperature. Due to these variables, in the same units (eg. %m/m) and at the same set of temperature and pressure (SLC or STP) you can compare the solubility values.
What is the solubility of nitrogen in water?
Very low, ranging about 1-5 ppm, lower than oxygen which is about 3-10 ppm (parts per million) at room temperature
What is solubility of chromium?
If At 25 Degrees C, the molar solubility of barium chromate in water is 1.1 x 10^-5 M. Here is how you would find the solubility in grams per liter.First: You must know the molar mass of Barium Chromate To continue. Look at your periodic Table.[BariumChromate Molar mass=253.37 g/mol]*Get this by adding together atomic number of each element in BaCrO4*253.37= Ba+Cr+O(4), or 137.33+52+16(4)*Take 1.1 x 10^-5 M and divide by molar mass of Barium Chromate1.1 x 10^-5 mol/L x 253.37 =0.002787Answer in grams per liter to three significant figures=2.787 x 10^-3 g/LHow many liters of water are required to dissolve 1 of barium chromate?*take 1gram BaCrO4 / 2.787 x 10^-3 g/L --------> Grams Cancel=2.787 x 10^-3 LAnswer in liters to three significant figures =359.71 LitersWhat is the solubility of barium chromate in parts per million?*parts per million = Grams of Solute/grams of solution X 10^6 (which is ppm)2.787 x 10^-3g/L x 1L/1000g x 10^6 = 0.02779, or 2.78 x 10^-2ppmAnswer in parts per million to three significant figures=2.78ppm**For dilute aqueous solutions, ppm is equivalent to units of mg/l
What is the name of BaCl2.2H2O?
Barium Dichloride is NOT correct. The name is Barium Chloride it is a binary ionic compound.
How much is 10 parts per million?
If you have 1 million parts of something 10 parts would be 10 parts per million. If you had 2 million parts of something 20 parts would be 10 parts per million.
What does the word 'sulfate' suggest about a chemical with that in its name?
There are two parts to this question:1) What is a sulfate? -- A sulfate is any molecule that has the ion SO42- in it. That ion is called "sulfate".2) What chemical properties are conferred on sulfates? -- There are no consistent properties across all sulfates, and many more relevant properties derive from the atom paired with the sulfate in an ionic compound. That being said, most sulfates will dissolve easily in water, especially sulfiric acid (H2SO4) which is a strong acid. However, the most commonly used sulfates, like gypsum and barium sulfate are not actually very soluable. Sulfates can often serve as ligands in certain instances.
What is the abbreviation for parts per million?
parts per million = ppm
How many PPM is 4.8 milligrams per liter?
There are one million milligrams in one liter. 4.8 milligrams is 4.8 parts per million (parts per million) There are one million milligrams in one liter. 4.8 milligrams is 4.8 parts per million (parts per million)
When was More Parts per Million created?
More Parts per Million was created in 2004.
