How many moles of calcium atoms are in 45.8 g of Ca?

To determine the number of moles of calcium atoms in 45.8 g of Ca, first find the molar mass of calcium (Ca) from the periodic table (40.08 g/mol). Then, divide the given mass by the molar mass of Ca to get the number of moles. In this case, 45.8 g of Ca is equal to 1.14 moles of Ca atoms.

A compound was analyzed and found to contain 13.5 g Ca 10.8g O and 0.675 g H what is the empirical formula of the compound?

First, determine the moles of each element: moles of Ca = 13.5 g / 40.08 g/mol = 0.336 moles moles of O = 10.8 g / 16.00 g/mol = 0.675 moles moles of H = 0.675 g / 1.01 g/mol = 0.668 moles Next, divide each mole value by the smallest mole value to get the ratio of atoms. The ratio is roughly 0.5 Ca to 1 O to 1 H. Therefore, the empirical formula of the compound is Ca(OH)2.
