It depends on the substance. Remember that moles are a unit of amount, and one mole is 6.02 × 1023 atoms. So if you have lead and hydrogen, they are obviously going to weigh differently. It would take far fewer atoms of lead to amount to 1 gram; therefore, less moles. However, one hydrogen atom has far less mass than one lead atom, and would need more atoms (and moles) to make one gram.
1 g silicon is equal to 0,0356 moles.
1 g of ammonia (NH3) is equal to 0,059 mol.
The answer is 0,615 moles.
79.5 g of CuO = 1 g So, 3.2 g = (1*3.2) / 79.5 = 0.04 mole
4 g of helium is equivalent to 1 mole of helium
1 g silicon is equal to 0,0356 moles.
There are approximately 0.023 moles of ammonia in 1 g of ammonia (NH3).
1 g of ammonia (NH3) is equal to 0,059 mol.
The answer is 0,615 moles.
79.5 g of CuO = 1 g So, 3.2 g = (1*3.2) / 79.5 = 0.04 mole
4 g of helium is equivalent to 1 mole of helium
The answer is 1.35 moles.425 g of UF4 would be 1.35 moles.
40 g of Ca = 1 mole So 808 g of Ca = 20.2 mole
1 g of sodium sulfite is equivalent to 0,0079 moles.
10 moles of sodium chloride have 584,397 g.
To determine how many moles of octane are present in 16.0 g, you would divide the mass of octane by its molar mass. The molar mass of octane (C8H18) is approximately 114.23 g/mol. Therefore, 16.0 g ÷ 114.23 g/mol = 0.14 moles of octane.
To find the moles of NaHCO3 in a 3.00 g sample, first calculate the molar mass of NaHCO3 (84.01 g/mol). Then, divide the mass of the sample by the molar mass to obtain the moles of NaHCO3. For this sample, 3.00 g / 84.01 g/mol ≈ 0.036 moles of NaHCO3 are present.
