What is the mass of 2.25 moles of magnesium sulfide?
To calculate the mass of 2.25 moles of magnesium sulfide (MgS), first determine its molar mass. Magnesium (Mg) has a molar mass of approximately 24.31 g/mol, and sulfur (S) has a molar mass of about 32.07 g/mol. Therefore, the molar mass of MgS is 24.31 g/mol + 32.07 g/mol = 56.38 g/mol. Multiplying the molar mass by the number of moles gives: 2.25 moles × 56.38 g/mol = 127.78 grams.
How many moles of MgS2O3 are in 209 grams of the compound?
To find the number of moles of MgS₂O₃ in 209 grams, you first need to calculate the molar mass of MgS₂O₃. The molar mass is approximately 120.37 g/mol (Mg: 24.31 g/mol, S: 32.07 g/mol x 2, O: 16.00 g/mol x 3). Then, divide the mass of the compound by its molar mass: ( \text{moles} = \frac{209 \text{ g}}{120.37 \text{ g/mol}} \approx 1.74 ) moles.
What is the molar mass of the sugar called glucose?
The molar mass of glucose is 180,16 g.
Is the empirical formula molar mass less than or equal to the actual molar mass for all compound?
The empirical formula molar mass is the mass of the simplest whole-number ratio of the elements in a compound, while the actual molar mass corresponds to the molar mass of the compound's molecular formula. The empirical formula molar mass is always less than or equal to the actual molar mass because the empirical formula represents the smallest ratio of atoms, which can be multiplied to obtain the molecular formula. Therefore, for compounds with a molecular formula that is a multiple of the empirical formula, the empirical molar mass will be less than the actual molar mass.
What is the molar mass of PbSO4?
The molar mass of PbSO4 (lead(II) sulfate) is approximately 303.3 g/mol. This can be calculated by adding the molar masses of each element in the compound: lead (Pb) has a molar mass of 207.2 g/mol, sulfur (S) has a molar mass of 32.1 g/mol, and oxygen (O) has a molar mass of 16.0 g/mol.

What is the molarity of 22.5 g of MgS in 817 ml of solution?
To calculate molarity, you first need to determine the number of moles of MgS. Calculate the molar mass of MgS: Mg: 24.3 g/mol S: 32.1 g/mol Molar mass of MgS = 24.3 g/mol + 32.1 g/mol = 56.4 g/mol Number of moles of MgS: 22.5 g / 56.4 g/mol = 0.398 moles Calculate molarity: Molarity = moles / volume of solution (in liters) Molarity = 0.398 moles / (817 ml / 1000) = 0.487 M

What is molar mass of iron?
The molar mass of iron is 55.845g per mol. Molar mass is the mass of a given substance divided by its amount of substance.
How can one determine the molar mass from molality?
To determine the molar mass from molality, you can use the formula: Molar mass (molality x molar mass of solvent) / molality of solute. This equation helps you calculate the molar mass of a substance based on its molality in a solution.
What is the molar mass of Klonopin?
The molar mass of Klonopin is 315,715 g.
What is the molar mass of lithium oxide Li2O?
Lithium has a molar mass of 6.94 g/mol. Oxygen has a molar mass of 16.00 g/mol. Since Lithium Oxide has 2 Lithium atoms, the molar mass is: (6.94 x 2) + 16.00 = 29.88 g/mol.
