1 mole of calcium = 40.078
so take 57.98/40.078=1.446679
2,8 moles of calcium carbonate have 240,208 g.
To find the number of moles in 3.75 grams of calcium, divide the mass of calcium by its molar mass. The molar mass of calcium is approximately 40.08 g/mol. Therefore, 3.75 grams of calcium is equal to 0.0936 moles.
126 grams calcium (1 mole Ca/40.08 grams) = 3.14 moles of calcium ------------------------------
To find the number of moles in 12.2 grams of calcium, divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. Dividing 12.2 grams by 40.08 g/mol gives approximately 0.305 moles of calcium.
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.
42,5 grams calcium is equivalent to 1,06 moles.
120 grams of calcium contain 2,994 moles.
7,68 grams of calcium nitride is equal to 0,052 moles.
There are 5 moles of calcium in 200 grams of calcium. This calculation is based on the molar mass of calcium, which is approximately 40 grams per mole.
3 moles of calcium is equivalent to 120,234 g.
0,27 moles of calcium contain 10,82 g calcium.
To find the number of moles in 5000 grams of calcium, you need to divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. So, 5000 grams of calcium is equal to 5000/40.08 = 124.69 moles of calcium.
3.8 grams calcium (1 mole Ca/40.08 grams) = 0.09 moles calcium ==============
120 g calcium is equal to 3 moles.
2,8 moles of calcium carbonate have 240,208 g.
The answer is 2,096.10e-4.
To find the number of moles in 3.75 grams of calcium, divide the mass of calcium by its molar mass. The molar mass of calcium is approximately 40.08 g/mol. Therefore, 3.75 grams of calcium is equal to 0.0936 moles.
