How many moles are equivalent to 3.6x1024 formula units of MgBr2?
The answer is 5,978 moles.
What is the mass of 7 mole of h2o?
To find the mass of 7 moles of water (H₂O), first note that the molar mass of water is approximately 18 grams per mole. Therefore, the mass of 7 moles of water can be calculated by multiplying the number of moles by the molar mass: 7 moles × 18 g/mol = 126 grams. Thus, the mass of 7 moles of H₂O is 126 grams.
What is the Molarity of a substance that contains 4.13 grams of magnesium bromide in 845 liters of a solution?
Molarity= mols/ L So, take 4.13g MgBr2 ( because Mg has a +2 charge and Bromide has a +1 charge) and divide it by 184.1 g MgBr2 which gives you .022 mols of MgBr2 then you divide .022 by 845 which gives you 2.65 M Molarity = 2.65M
Formula for magnesium bromide?
The chemical formula of magnesium dibromide is MgBr2.
Convert grams to moles?
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
How many anions are there in 2.50 g of MgBr2?
There are a total of 2 moles of anions in 2.50 g of MgBr2. Each formula unit of MgBr2 contains 2 moles of anions (Br-). The molar mass of MgBr2 is 184.113 g/mol, so 2.50 g is equivalent to 0.0136 moles, and therefore 0.0136 moles * 2 moles = 0.0272 moles of anions.
How many moles of bromide ions are present in 750.0 mL of 1.35 M MgBr2?
There are 1.35 moles of MgBr2 in 1 L of solution, which corresponds to 2 moles of bromide ions. Therefore, in 750.0 mL of 1.35 M MgBr2 solution, there will be 1.0125 moles of bromide ions.
How many moles are equivalent to 3.6x1024 formula units of MgBr2?
The answer is 5,978 moles.
What is the mass of 7 moles of argon?
Mass of 1mole of Argon is 39.95g. So, The mass of 7 moles of Argon is 39.95x7= 279.65g.
How many anions are there in 3.50 g of MgBr2?
There are 0.021 moles of MgBr2 in 3.50 g. Since MgBr2 contains 2 bromide ions per formula unit, there are 0.042 moles of Br- ions. So, there are 0.042 * 6.022 x 10^23 = 2.53 x 10^22 Br- ions in 3.50 g of MgBr2.

The mass of 7 050 moles of natural uranium is 238,02891 x 7 050.
How many grams are in 1.11 moles of manganese sulfate Mn3SO47?
To calculate the number of grams in 1.11 moles of manganese sulfate (Mn3(SO4)7), you need to find the molar mass of the compound. The molar mass of Mn3(SO4)7 is approximately 678.88 g/mol. Therefore, 1.11 moles of Mn3(SO4)7 would be equal to 1.11 moles x 678.88 g/mol ≈ 753.38 grams.
How many moles of gold are in 3.60x10-5g of gold?
To find the number of moles of gold, first calculate the molar mass of gold, which is 197 g/mol. Then, divide the given mass of gold by the molar mass to find the number of moles. In this case, 3.60x10-5g ÷ 197 g/mol ≈ 1.83x10-7 moles of gold.
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
