Convert moles to atoms by using Avogadro's number. Number of atoms= Avogadro's Number× Number of moles where, Avogadro's Number=6.022×1023 Step 3: Find the weight of the substance from the expression, Weight of the given substance=Number of AtomsAvogadro Number×Molar mass Interco...
In summary, using the ideal gas law, we can determine the number of moles of gas in a 7.71 liter vessel at a temperature of 18.6oC and a pressure of 8.35 atm. We can use the formula # of moles = (pressure * volume) / (gas constant * temperature) to find that t...
be used to determine the simplest formula of acompoundand to calculate the quantities involved inchemical reactions. When dealing with reactions that take place insolutions, the related concept ofmolarityis useful. Molarity (M) is defined as the number of moles of a solute in alitreof solution...
First, convert the grams to moles using the molar mass and then use Avogadro's number to find the number of molecules: \(\mathrm{2g\enspace NaCl\Biggl(\dfrac{1mol\enspace NaCl}{58.44g\enspace NaCl}\Biggr)\Biggl(\dfrac{6.022\times10^{23}\enspace molecules\enspace NaCl}{1mol}\Big...
The formula weight of CaCl2 is therefore (1 x 40.08) + (2 x 35.45) = 100.98. Step 3 Calculate the number of moles for any compound in the balanced equation for which you know the mass. The masses of all other substances can be calculated from the mass of just one product or react...
To determine the number of moles of sulfuric acid (H₂SO₄) in 98 grams, follow these steps:Step 1: Identify the formula of sulfuric acid The chemical formula for sulfuric acid is H₂SO₄.Step 2: Calculat
Number of gram atoms=26.022≈0.33 gram atoms Step 3: Calculate the weight of the elementTo find the weight of the element, we can use the formula: Weight=Number of moles×Molar mass We already calculated the number of gram atoms, which is equivalent to the number of moles (since 1 gram...
