20 protons from calcium and 17 from each chlorine. So total of 54 protons.
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)
Beryllium has 4 protons
Calcium chloride (CaCl2) is a compound that forms by combining one calcium ion (Ca2+) with two chloride ions (Cl-).
You can tell how many protons an element has from its atomic number. So the atomic number of Strontium is 38..so it has 38 protons.
This depends of the concentration of CaCl2 in this solution.
There are 0.07871604895385 moles of CaC12 in 14.5g of CaC12.
There is 1 atom of calcium in CaCl2. Each molecule of CaCl2 contains 1 calcium atom, 2 chlorine atoms, and a total of 3 atoms.
Three.
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 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.
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.
The dissociation equation for CaCl2 in water is: CaCl2 (s) → Ca2+ (aq) + 2Cl- (aq)
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.
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.
The name of CaCl2 is Calcium Chloride
