How many formula units are present in 2.50 moles of CaCl2?
There are 3.01 x 10^24 formula units of CaCl2 in 2.50 moles. This can be calculated using Avogadro's number (6.022 x 10^23) and the formula units present in one mole of CaCl2 (3).
How many moles of CaCl2 are in 2.00 1024 formula units?
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.
How many grams of CaCl2 can be obtained if 14.6 g HCl is allowed to react with excess CaCO3?
The balanced chemical equation for the reaction between HCl and CaCO3 is: 2HCl + CaCO3 → CaCl2 + H2O + CO2. The molar ratio between HCl and CaCl2 is 2:1. Calculate the number of moles of HCl from 14.6 g, then use the mole ratio to find the moles of CaCl2. Finally, convert moles of CaCl2 to grams.
How many grams are in 0.74 moles of CaCl2?
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
How many moles of solute are contained in the following solution 17.33 mL 2.17 M CaCl2?
To find the moles of solute, first calculate the amount of CaCl2 in the solution: 17.33 mL * 2.17 mol/L = 37.6561 mmol of CaCl2. Then convert this to moles: 37.6561 mmol / 1000 = 0.0377 mol of CaCl2 in the solution.

How many moles of CaCl2 are in 14.5 g of CaCl2?
There are 0.07871604895385 moles of CaC12 in 14.5g of CaC12.
How many moles of solutes in 2.10 ml CaCl2?
This depends of the concentration of CaCl2 in this solution.
How many moles of CaCl2 contain 1.261024 formula units 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.
How many grams of CaCl2 equal 3.40 moles of CaCl2?
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.
How many moles of CaCl2 are in 2.00 1024 formula units?
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.
7.5 grams of CaCl2 is how many moles?
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
