================================
There are 0.07871604895385 moles of CaC12 in 14.5g of CaC12.
2.430 moles CaCl2 x 110.98 g CaCl2/mole CaCl2 = 269.7 grams (4 sig figs)
As thenumber of molecules incresses so does the volume
Multiply the number of moles by Avogadro's number (6.022 x 1023).CONVERSION FACTORNumber of moles X Avogadro's Number////////////////////////////// 1 mole
No. Take the microbial hydrogen mechanism as an example:4H2 + CO2 --> CH4 + 2H2O5 moles of reactants on the left converts to 3 moles of products on the right. The total number of moles of each type of atom does balance however.
To find the number of molecules in 1.46 moles of CaCl2, you need to use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole. Therefore, the number of molecules in 1.46 moles of CaCl2 would be 1.46 * 6.022 x 10^23.
The molar mass of CaCl2 is 110.98 g/mol. To find the mass of 3.40 moles of CaCl2, you would multiply the number of moles by the molar mass: 3.40 moles x 110.98 g/mol = 377.192 g. Therefore, 3.40 moles of CaCl2 is equal to 377.192 grams of CaCl2.
To calculate the number of moles of CaCl2, you first need to find the molar mass of CaCl2, which is 110.98 g/mol. Then, you divide the given number of formula units (1.261024) by Avogadro's number to convert it to moles. So, the answer would be approximately 1.14 moles of CaCl2.
To find the number of moles of CaCl2 in 2.00x10^24 formula units, you need to first determine the molar mass of CaCl2, which is 110.98 g/mol. Then, divide the number of formula units by Avogadro's number (6.022x10^23) to convert to moles. This gives you approximately 3.32 moles of CaCl2.
To find the number of moles of CaCl2, first calculate the molar mass of CaCl2: Ca: 40.08 g/mol Cl: 35.45 g/mol (x2 since there are two Cl atoms) Total molar mass: 40.08 + 35.45(2) = 110.98 g/mol Next, calculate the number of moles: 2.41 x 10^24 formula units / Avogadro's number (6.022 x 10^23) = 4 moles of CaCl2.
To find the number of moles in 140 g of CaCl2, you need to divide the given mass by the molar mass of CaCl2. The molar mass of CaCl2 is 110.98 g/mol. So, 140 g / 110.98 g/mol = 1.26 moles of CaCl2.
Oh, dude, let me break it down for you. So, 1 mole of CaCl2 contains 6.022 x 10^23 formula units, right? And you've got 1.26 x 10^24 formula units of CaCl2. So, you just divide 1.26 x 10^24 by 6.022 x 10^23 to get the number of moles. Easy peasy, lemon squeezy!
For this you need the atomic (molecular) mass of CaCl2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. CaCl2=111.1 grams7.5 grams CaCl2 / (111.1 grams) = .0675 moles CaCl2
To convert from number of molecules to moles, we use Avogadro's number: 1 mole = 6.022x10^23 molecules. Therefore, 1.0x10^19 HCl molecules is equal to 1.66x10^-5 moles of HCl.
To convert molecules to moles, divide the number of molecules by Avogadro's number (6.022 x 10^23). Therefore, 3.4 x 10^23 molecules of H2SO4 is equal to approximately 0.056 moles.
Atomic Weight of Calcium = 40 Atomic Weight of Chlorine = 35.5 Therefore, 1 mole of CaCl2 => 40 + 2 (35.5) = 111 g 0.74 moles of CaCl2 => 0.74 (111) = 82.14 g
There are 0.07871604895385 moles of CaC12 in 14.5g of CaC12.
