What mass of calcium bromide is needed to prepare 250 ml of a 2.50M?
The answer is 124,93 g (for the anhydrous CaBr2).
What is the percent mass of calcium in a calcium supplement if 1.35-g of calcium carbonate is extracted from a 2.36-g pill?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. To calculate the percent mass of calcium, you need to divide the molar mass of calcium (40.08 g/mol) by the molar mass of calcium carbonate. This gives you a result of 0.4006, meaning that calcium constitutes approximately 40.06% of the mass of calcium carbonate.
What compound is made from calcium and bromine?
Calcium bromide is the compound made from calcium and bromine. It is an inorganic compound used in various industries like drilling fluids, chemical synthesis, and as a sedative in medicine.
Percent calcium ion in calcium carbonate?
Calcium carbonate (CaCO3) consists of one calcium ion (Ca2+) and one carbonate ion (CO3^2-). Therefore, the percentage of calcium ions in calcium carbonate is calculated as: (Atomic mass of calcium / Molecular mass of calcium carbonate) x 100 = (40.08 / 100.09) x 100 = 40.02% Therefore, calcium ions make up approximately 40.02% of the total mass of calcium carbonate.
What is calcium bromine?
Calcium bromine is not a naturally occurring compound. However, calcium bromide is a chemical compound composed of calcium and bromine that is used in various industrial applications, such as drilling fluids, food preservatives, and pharmaceuticals.
What is the molar mass calcium bromide?
The molar mass of calcium bromide (CaBr2) is approximately 199.89 g/mol.
How many moles are in 7.4 kilogram of calcium bromide?
To find the number of moles in 7.4 kg of calcium bromide, you first need to convert the mass to grams (1 kg = 1000 g). Next, calculate the molar mass of calcium bromide (CaBr2) which is approximately 199.89 g/mol. Finally, divide the mass in grams by the molar mass to find the number of moles.
How many moles are in 1.2 kilograms of calcium bromide?
To find the number of moles in 1.2 kg of calcium bromide, you first need to determine the molar mass of calcium bromide (CaBr2), which is approximately 199.89 g/mol. Then convert the mass of 1.2 kg to grams (1200 g). Finally, divide the mass in grams by the molar mass to find the number of moles. In this case, 1200g / 199.89g/mol ≈ 6 moles of calcium bromide.
What mass of calcium bromide is needed to prepare 150.0 mL of a 3.50 M solution?
To calculate the mass of calcium bromide needed, you would first find the number of moles needed using the equation moles = Molarity * Volume (in liters). Then, you would use the molar mass of calcium bromide to convert moles to grams. The molar mass of calcium bromide is 199.89 g/mol.
What ionic compound is Ca Br?
The ionic compound calcium bromide is CaBr2.
Is calcium bromide acidic?
No, calcium bromide is not acidic. It is a salt compound composed of calcium and bromide ions, and it is typically neutral in pH.
What is the name of ionic compound CaBr2?
The ionic compound CaBr2 is called calcium bromide.
What is the percent by mass of calcium in the compound (CaSO4)?
The molar mass of CaSO4 is approximately 136.14 g/mol. The molar mass of calcium in CaSO4 is 40.08 g/mol. To find the percent composition of calcium in CaSO4, divide the molar mass of calcium by the molar mass of CaSO4 and multiply by 100. The percent by mass of calcium in CaSO4 is approximately 29.45%.
Is calcium bromide acide or base?
Calcium bromide is neither an acid nor a base. It is a salt composed of calcium cations and bromide anions.
