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 of 4.75 moles of arsenic trichloride (AsCl3?
To calculate the mass of 4.75 moles of arsenic trichloride (AsCl3), first determine its molar mass. The molar mass of AsCl3 is approximately 133.33 g/mol (75 g/mol for arsenic and 3 × 35.45 g/mol for chlorine). Therefore, the mass can be calculated as follows: Mass = moles × molar mass = 4.75 moles × 133.33 g/mol ≈ 632.49 g. Thus, the mass of 4.75 moles of AsCl3 is approximately 632.5 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.
Toxic chemicals in drinking water usually are reported and a safety level specified in units of parts per million ppm by mass Show how to calculate the molar concentration of arsenic in a water sam?
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
What is the atomic mass of arsenic?
The atomic mass of arsenic is approximately 74.92 atomic mass units.
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?
To convert moles to grams, you need to know the molar mass of arsenic. Arsenic has a molar mass of approximately 74.92 g/mol. Therefore, to find the grams in 238 moles of arsenic, you would multiply the number of moles by the molar mass: 238 moles x 74.92 g/mol = 17,827.76 grams of arsenic.
How many grams in 238 moles of arsenic?
The conversion factor you need for this problem is the atomic mass of titanium.47.9 gram titanium = 1 mole titaniumSince you want to end up in units of grams of Ti, this goes in the numerator (on top). You want to convert from moles Ti, so this goes in the denominator (on the bottom).moles Ti47.9 gram Ti = grams Ti1 moles Ti
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 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.
