1 moles CF4 = 88.0043128 grams.
CF4 = 171 grams / 88 grams = 1.9431 moles
To find the number of moles in 171 g of CF4, you first need to calculate the molar mass of CF4. Carbon has a molar mass of 12.01 g/mol and each fluorine atom has a molar mass of 19.00 g/mol, giving a total molar mass of CF4 as 88.01 g/mol. Then divide 171 g by the molar mass of CF4 to get the number of moles.
1.94 mol
To calculate the mass of 7.801018 carbon atoms, you would multiply the number of atoms by the atomic mass of carbon (12.011 amu). Therefore, the mass would be 7.801018 x 12.011 amu = 93.68 amu.
To calculate the number of molecules, first determine the molar mass of carbon tetrafluoride (CF4), which is 88.004 g/mol. Next, divide the given mass (8.69 g) by the molar mass to find the number of moles. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
3,80 g Zn have 0,058 moles.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,364 moles.

3,80 g Zn have 0,058 moles.
The formula is: number of moles = g Be/9,012.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,4 moles.
The answer is 0,364 moles.
To find the number of moles in 19.2 g of CS2, we need to divide the given mass by the molar mass of CS2. The molar mass of CS2 is 76.14 g/mol. So, 19.2 g รท 76.14 g/mol โ 0.252 moles of CS2.
573,28 of g of AgCI is equivalent to 4 moles.
978 g calcium contain 24,4 moles.
14,84 g magnesium are equivalent to 0,61 moles.
67,4 g HCl is equivalent to 1,85 moles.
