To find the number of moles of POCl3 in 10.0 grams, you first need to calculate the molar mass of POCl3. The molar mass is approximately 30.97 g/mol (P) + 16.00 g/mol (O) + 3 × 35.45 g/mol (Cl) = 137.32 g/mol. Using the formula: moles = mass (g) / molar mass (g/mol), you would calculate moles = 10.0 g / 137.32 g/mol, which is approximately 0.073 moles of POCl3.

How many grams of argon are in 100 mole?
To find the mass of argon in grams for 100 moles, you can use the molar mass of argon, which is approximately 40 grams per mole. Therefore, the mass of 100 moles of argon would be calculated as follows: 100 moles × 40 g/mole = 4000 grams. Thus, there are 4000 grams of argon in 100 moles.
What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
How many litters of 4M solution can be made using 100 grams of lithium bromide?
To determine how many liters of a 4M lithium bromide (LiBr) solution can be made from 100 grams of LiBr, we first need to calculate the number of moles in 100 grams. The molar mass of lithium bromide is approximately 86.84 g/mol, so 100 grams corresponds to about 1.15 moles. A 4M solution contains 4 moles of solute per liter, thus 1.15 moles can produce approximately 0.29 liters (1.15 moles ÷ 4 moles/L). Therefore, 100 grams of lithium bromide can make about 0.29 liters of a 4M solution.
