5,00 g of BH3 is equal to 0,36 moles.
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.
To find the weight of 500 moles of CuBr, you first need to determine the molar mass of CuBr which is 159.43 g/mol. Then, you can calculate the weight by multiplying the number of moles by the molar mass: 500 moles * 159.43 g/mol = 79,715 g.
The molar mass of ammonia is 17,031 g.17,031 g NH3-------------------1 mol500 g NH3-------------------------xx= 500/17,031 = 29,36 moles
The formula is: number of moles = g Be/9,012.
14,84 g magnesium are equivalent to 0,61 moles.
97,5 g of oxygen is equal to 5,416 moles.
978 g calcium contain 24,4 moles.
573,28 of g of AgCI is equivalent to 4 moles.
67,4 g HCl is equivalent to 1,85 moles.
29,0 g of calcium is equal to 0,723 moles.
27.4 g H2O x 1 mole/18 g = 1.52 moles
For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.11.5 grams Na / (23.0 grams) = .500 moles Na
156 g calcium is equivalent to 3,89 moles.
