How many anions are there in 3.50 g of MgBr2?
There are 22,9.10e21 anions.
How many moles of anions are in 37.4 g of AlF3?
1.33
What is the percent composition of a compound containing 32.0 g of bromine and 4.9 g of magnesium?
Total mass of MgBr2- 36.9 g Mass of Br 32.0 / total mass 36.9 = .867 = 86.7% Mass of Mg 4.9 / 36.9 = .133 = 13.3% There is 86.7% of Bromine and 13.3% of Magnesium in the compound MgBr2
How many electrons does 250 ml of water contains?
As you know the density of pure water is 1 g/ml. so the mass of 250 ml water is 250 g. Now the no of molecules of water present in 250 g of water = 250 x 6 x 1023/18 = 8.33 x 1024 Now each molecule of water contains total 10 electron. So total no. of electrons in 250 g of water are 10 x 8.33 x 1024 = 8.33 x 1025 electrons.
How many moles are there in 250 g of CaCO3?
250 grams CaCO3 (1 mole CaCO3/100.09 grams) = 2.50 moles of calcium carbonate
How many anions are there in 3.50 g of MgBr2?
There are 22,9.10e21 anions.
How many moles of anions are in 37.4 g of AlF3?
1.33
What is the mass of 7 moles of MgBr2?
The molar mass of MgCl2 = 95.211 g/mol
How many moles of anions are in 38.8 g of AlF3?
1.39 moles
How many moles of anions are in 33.4 g of AlF3?
molar mass AlF3 = 83.98 g/mole33.4 g AlF3 x 1 mole/83.98 g = 0.398 molesEach mole of AlF3 contains 3 moles of F- anions, because AlF3 ==> Al^3+ + 3F^-.Thus, moles of anions = 3 x 0.398 = 1.19 moles of anions
How many pounds in 250 grams?
250 g = about 0.55116 pounds.
How many kg equals 250 g?
250 g = 0.25 kgTo convert from g to kg, divide by 1000.
How many grams are in 250 mg?
250 mg = 0.25 g
How many times does 250g go into 1 ton?
1 tonne = 1,000,000 g ⇒ 1 tonne ÷ 250 g = 1,000,000 g ÷ 250 g = 4,000
What is the percent composition of a compound containing 32.0 g of bromine and 4.9 g of magnesium?
Total mass of MgBr2- 36.9 g Mass of Br 32.0 / total mass 36.9 = .867 = 86.7% Mass of Mg 4.9 / 36.9 = .133 = 13.3% There is 86.7% of Bromine and 13.3% of Magnesium in the compound MgBr2
How many kilograms are there in 48 250 grams?
48 250 g = 48.25 kgTo convert from g to kg, divide by 1000.
