What is the relative formula mass of each of the following compounds of potassium dichromate?
The relative formula mass of potassium dichromate (K2Cr2O7) is calculated by adding the atomic masses of its individual elements. The atomic masses of potassium (K), chromium (Cr), and oxygen (O) are 39.1, 52, and 16 respectively. Therefore, the relative formula mass of potassium dichromate is 294.2 g/mol.
How many mmol equal 52 meq of potassium?
Since potassium has a valence of one, its equivalent weight is the same as its molecular weight; therefore, 2.9.
What is the percent composition of potassium phosphate?

What element has mass number 52?
Chromium is a metallic element. Mass number of it is 52.
What are the seventeen isotopes in potassium?
I believe 24 isotopes have been identified with atomic mass ranging from 32 to 55. Only three occur naturally, K39 (93% of the total), K41 (7%) and the radioactive K40 (0.01%). The others have very short half-lives, as small as a few nano-seconds in some cases.
What is the element with a mass number 52?
The element with a mass number of 52 could be tellurium (Te) or antimony (Sb). Both of these elements have isotopes with a mass number of 52.
What mass of barium bromide needed to precipitate the silver ions from 100 ml of 52 M silver nitrate solution?
The equation of the reaction is BaBr2 + 2 AgNO3 -> 2 AgBr + Ba(NO3)2. Therefore, exactly as many bromide ions from barium bromide must be supplied to precipitate any particular number of silver ion from silver nitrate. From the definition of molarity, 100 ml of 52 M solution contains 5.2 moles (preferably called "gram formula units") of silver nitrate. The gram formula unit mass of silver nitrate is 169.87, and each gram formula mass contains equal numbers of silver and of nitrate ions. Therefore, 5.2 gram elemental masses of bromide ions will be required for the precipitation. This amount of bromide ions can be supplied by 5.2/2* or 2.6 gram formula masses of barium bromide, and the gram formula unit mass of barium bromide is 297.14. Multiplying this number by 2.6 shows that 7.7 X 102 grams of barium bromide, to the justified number of significant digits, will be needed.
Does honey have much potassium?
According to the USDA: 52 mg of potassium per 100 grams of honey (5 tablespoons)
Which element is a transition element with a mass of 52?
The element with a mass number of 52 is Chromium (Cr). It's atomic number is 24.
What is the integer that represents a loss of 52 lbs Then what is the opposite of that integer?
-52 and 52
How much is 52 kilo grams in lbs pounds weight?
52 kilograms is a measure of mass, not of weight. A mass of 52 kilograms would weigh approx 509.6 Newtons on the surface of the earth. This converts to approx 3668 pounds weight. 52 kg is mass, but is equivalent to 2.2 pounds weight; thus 52 kg is equivalent to 2.2 x 52 = 114 pounds
What is atomic mass of atom ethyne?
52
