The formula for H3BO3 is boric acid. The molecular weight of boric acid is 61.83-grams per mole. Thus, the given sample of 61.83-grams equals 1.00-moles of H3BO3.
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 determine the number of moles in 382 g of cobalt (Co), first calculate the molar mass of cobalt, which is approximately 58.93 g/mol. Then, divide the given mass by the molar mass to obtain the number of moles. Moles = 382 g / 58.93 g/mol = approximately 6.48 moles of Co atoms.
