Molecular mass , moles and atoms worksheet. Molecular mass , moles and atoms worksheet: Here are some questions or a worksheet related to molecular mass , mole concept and atoms. The questions here are related to the measurement of molecular weight in different units and measurement of different entity of molecules and atoms. Questions: 1.

The ideal gas law is PV = nRT. Coomon units for pressure, volume, n, and temperature are atmospheres, liters, moles, and Kelvin, respectively. R is a constant, which has a value of 0.08206 (l*atm)/(K*mol). 2. If you know the number of moles of an ideal gas, what is the minimum number of

Period: Worksheet: Molar Volume/Molar Mass #1. 1. How many moles of molecules are contained in 78.4 l of Neon at STP? 2. What is the volume of 0.8 moles of Chlorine gas at STP? 3. How many molecules are contained in 16.8 l of Xe at STP? 4. How many moles of molecules are contained in 39 l of F2 gas at STP? 5.

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*10 23 * 55.556 = 3.346*10 25 molecules. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*10 26 atoms in a liter of water. Now we know enough to answer your question.

The findings of 19thcentury chemists and physicists, among them Avogadro, Gay-Lussac, Boyle and Charles, are summarized in the Ideal Gas Law: PV = nRT. P= pressure V= volume n= moles of gas, R= universal gas constant T= temperature. The value of Rvaries with the units chosen: R= 0.08206 L atm / mol K R= 8.314 J /mol K.

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*10 23 * 55.556 = 3.346*10 25 molecules. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*10 26 atoms in a liter of water. Now we know enough to answer your question.

From the reading on the scale, I see that the mass of the sample is 84.924 grams. The volume of the sample is 100.0 mL. (A volumetric flask is accurate to about 0.1 mL, so I know the volume to 4 significant figures.) I divide the mass by the volume to get 0.8492 g/mL, the density of the liquid.

Solutions to the Ideal gas law practice worksheet: The ideal gas law states that PV=nRT, where P is the pressure of a gas, V is the volume of the gas, n is the number of moles of gas present, R is the ideal gas constant, and T is the temperature of the gas in Kelvins. Common mistakes: Students express T in degrees celsius, rather than Kelvins.
