What else can I help you with?
What is the mass percent of calcium chloride if 45g of cacl2 is dissolved in 320 g of water?
Mass percent of calcium chloride can be calculated by dividing the mass of calcium chloride by the total mass of the solution (calcium chloride + water) and then multiplying by 100. In this case, the mass percent would be (45g / (45g + 320g)) * 100 ≈ 12.35%.
What is the molecular mass for calcium chloride?
Calcium chloride with formula CaCl2 has molecular mass of 141. Commercial calcium chloride has formula CaCl2,2H2O.It's molecular mass is 177.
How many grams calcium are in 100 grams calcium chloride?
The formula of anhydrous calcium chloride is CaCl2, and its gram formula mass is 110.99. The gram atomic mass of calcium is 40.08. Therefore, the grams of calcium in 100 grams of calcium chloride is 100(40.08/110.99) or 36.11 grams, to the justified number of significant digits.
A solution contains 30 g of calcium chloride in 250 g of water express the mass percent?
The solution has a total mass of 30 + 250 = 380 g. The mass percent of calcium chloride in this solution is 100(30/380) = 7.9 %, to the justified number of significant digits.
How do you find the molar mass of calcium chloride?
To find the molar mass of calcium chloride (CaCl₂), first identify the atomic masses of its constituent elements: calcium (Ca) has an atomic mass of approximately 40.08 g/mol, and chlorine (Cl) has an atomic mass of about 35.45 g/mol. Since there are two chlorine atoms in calcium chloride, calculate the molar mass as follows: 40.08 g/mol (Ca) + 2 × 35.45 g/mol (Cl) = 111.98 g/mol. Therefore, the molar mass of calcium chloride is approximately 111.0 g/mol.
How many moles of calcium ions are present in 166.5grams of calcium chloride?
The chemical formula for calcium chloride is CaCl2, and its formula weight is 110.99. The formula shows that each formula weight of calcium chloride contains one mole of calcium ions. In 166.5 grams, there are 166.5/110.99 or 1.500 formula weights of calcium chloride and the same number of moles of calcium ions.
How many atoms of chloride are in 654.5 grams of calcium chloride?
To find the number of chloride atoms in 654.5 grams of calcium chloride, you would first calculate the number of moles of calcium chloride using its molar mass. Then, since each formula unit of calcium chloride contains two chloride ions, you would multiply the number of moles by 2 to find the number of chloride atoms.
What is the word equation of calcium with hydrochloric acid?
One gram atomic mass of calcium reacts with two gram molecular masses of hydrochloric acid to form one gram formula mass of calcium chloride and one gram molecular mass of diatomic hydrogen gas.
Calcuate the mass of sodium chloride produced if 12.3 g of sodium oxide reacts with an excess of calcium chloride?
To calculate the mass of sodium chloride produced, first balance the chemical equation for the reaction between sodium oxide and calcium chloride. Next, determine the molar ratio between sodium oxide and sodium chloride in the balanced equation. Finally, use the given mass of sodium oxide and the molar mass of sodium chloride to calculate the mass of sodium chloride produced.
Is calcium chloride water solube?
Most metal halide salts are water-soluble, with a few exceptions. Calcium chloride is not one of these exceptions, and is quite soluble in water, in fact, at 300 K (just slightly above "room temperature"), a given mass of calcium chloride will dissolve in an equal mass of water.
How many molecules are in 654.5 grams calcium chloride?
To find the number of molecules in 654.5 grams of calcium chloride, you need to first convert the mass to moles using the molar mass of calcium chloride. Then, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules.
Difference between calcium chloride and fused calcium chloride?
Calcium chloride is a salt that is typically in the form of a solid or solution. Fused calcium chloride refers to the solid form of calcium chloride that has been heated to its melting point and then cooled to solidify. Fused calcium chloride has a higher purity and is often used in more specialized applications compared to regular calcium chloride.
