WebSep 3, 2024 · Obtain the atomic masses of each element from the periodic table and multiply the atomic mass of each element by the number of atoms of that element. 1 Ca atom = 40.078 amu. 1 P atom = 30.973761 amu. 1 O atom = 15.9994 amu. Add together the masses to give the formula mass. 3Ca: (3 atoms) (40.078 amu/atom)=120.234amu.

10.2: Conversions Between Moles and Atoms - Chemistry …
Web1) The first step is to convert grams to moles in the usual manner: 3.78 g / 18.015 g/mol = 0.209825 mol 2) The next step is to convert moles to number of molecules, a calculation that uses Avogadro's Number: (0.209825 mol) (6.022 x 1023mol¯1) = 1.26 x 1023molecules (rounded to three sig figs) WebMultiply the moles given by the substance's molar mass: 0.700 mole x 34.0146 grams/mole = 23.8 grams The answer of 23.8 g has been rounded to three significant figures because the 0.700 value had the least number of significant figures in the problem. 4) If this problem were set up like the proportion above, you would have this: x 34.0146 g WebMultiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams. The number of grams of KClO3 will be 306.37 And here is how you should enter this problem into the calculator above: moles to grams problem solution Similar calculators • Molar mass of the substance • Clapeyron-Mendeleev equation. john repke public service commissioner
