What is the mass of 4.75 moles of arsenic trichloride?
4,75 moles of arsenic trichloride (AsCl3) is equal to 181,28 g.
What is the mass for one mole of arsenic?
Arsenic is 74.9 grams per mole, so 1.9 grams would be 1.9/74.9=about 0.025 moles.
What is the atomic mass of arsenic?
The atomic mass is 74.9216 grams.
How many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
What is the mass of 4.75 moles of arsenic trichloride (AsCl3)?
4,75 moles of arsenic trichloride (AsCl3) is equal to 181,28 g.
What is the mass of 4.75 moles of arsenic trichloride?
4,75 moles of arsenic trichloride (AsCl3) is equal to 181,28 g.
How many gram are in 238 moles of arsenic?
Atomic mass of Arsenic = 74.9g/mol Using the formula: mass = Atomic mass x number of moles mass = 74.9g/mol x 238 mol = 17826.2 grams
What is the mass for one mole of arsenic?
Arsenic is 74.9 grams per mole, so 1.9 grams would be 1.9/74.9=about 0.025 moles.
How many atoms are there in 3.5 moles of arsenic?
In one mole of Arsenic contains 6.02 x 10^23 atoms. This is the Avogadro's number. So in 3.5 moles of Arsenic, there would accordingly be 2.11 x 10^24 atoms.A mole of As has the Avogadro number of moles. It is equivalent to 6.022 x 10^23. Therefore, 3.5 moles of the element contains 2.11 x 10^24 atoms of Arsenic.
What is mass number of arsenic?
Arsenic is a non metallic element. Mass number of it is 75.
Show how to calculate the molar concentration of arsenic in a water sample that has 1 ppm arsenic As?
1 ppm means one gram of arsenic per 1,000,000 grams of water 1,000,000 grams of water is 1,000 litres = 1,000 dm^3 (one gram = one ml) assuming we have this quantity of solution: moles arsenic = mass/Mr = 1/74.9 = 0.0133511348 moles but this is for 1,000 dm^3, so for 1 dm^3 we have 1000th of this amount, which is 1.335113485 x 10^-5 moles So the molar concentration is 1.34 x 10^-5 mol.dm^-3 (I hope)
What is the molar mass for FeCI3?
The molar mass of iron trichloride is 162,5 g for the anhydrous salt.
How many mass does arsenic have?
Atomic Mass: 74.9216 amu
What is the atomic mass of arsenic?
The atomic mass is 74.9216 grams.
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
