Molar mass of barium hydroxide, Ba(OH)2 = 171.3
Amount of barium hydroxide = mass of sample / molar mass = 317.0/171.3 = 1.85mol
To find the number of moles in 2400 grams of Ba(OH)2, divide the given mass by the molar mass of Ba(OH)2. The molar mass of Ba(OH)2 is 171.34 g/mol. So, 2400 g / 171.34 g/mol = 14.00 mol of Ba(OH)2.
27.4 g H2O x 1 mole/18 g = 1.52 moles
To find the number of moles in 4.5 g of AgNO3, you first need to determine the molar mass of AgNO3 which is 169.87 g/mol. Then you can use the formula: moles = mass / molar mass. Therefore, moles = 4.5 g / 169.87 g/mol ≈ 0.0265 moles.
To find the number of moles, you need to divide the given mass (in grams) by the molar mass of CCl4, which is 153.82 g/mol. Therefore, 56 g / 153.82 g/mol = 0.364 moles of CCl4.
To find the number of moles of argon in 24.7 g, you need to divide the mass of the sample by the molar mass of argon (39.95 g/mol). Therefore, 24.7 g of argon is equal to 0.62 moles (24.7 g ÷ 39.95 g/mol = 0.62 mol).
To find the number of moles in 2400 grams of Ba(OH)2, divide the given mass by the molar mass of Ba(OH)2. The molar mass of Ba(OH)2 is 171.34 g/mol. So, 2400 g / 171.34 g/mol = 14.00 mol of Ba(OH)2.
The formula is: number of moles = g Be/9,012.
