how many grams are in 5.66 mol of CaCO3? (the three is the subscript)
Wouldn't you take the molecular mass of calcium carbonate (one Ca atom, one C atom, and three O atoms) and multiply that by 5.66?
To find the number of grams in 5.66 moles of CaCO3, we need to use the molar mass of CaCO3.
The molar mass of an element or compound is the mass of one mole of that substance. It is calculated by adding up the atomic masses of all the atoms in the formula.
The formula for calcium carbonate (CaCO3) tells us that it consists of one calcium atom (Ca), one carbon atom (C), and three oxygen atoms (O).
Now, let's calculate the molar mass of CaCO3:
- The atomic mass of calcium (Ca) is 40.08 g/mol.
- The atomic mass of carbon (C) is 12.01 g/mol.
- The atomic mass of oxygen (O) is 16.00 g/mol.
To find the molar mass of CaCO3, we add up these atomic masses:
Molar mass = (1 x Ca) + (1 x C) + (3 x O)
= 40.08 g/mol + 12.01 g/mol + (3 x 16.00 g/mol)
= 40.08 g/mol + 12.01 g/mol + 48.00 g/mol
= 100.09 g/mol
Therefore, the molar mass of CaCO3 is 100.09 g/mol.
To find the number of grams in 5.66 moles of CaCO3, we can use the following equation:
Mass (in grams) = Number of moles x Molar mass
Substituting the given values:
Mass = 5.66 mol x 100.09 g/mol
Calculating this equation:
Mass = 566.74 grams
So, there are 566.74 grams in 5.66 moles of CaCO3.
