英语翻译use the general gas equation to determine the amount in moles of a gas,or its volume,temperature or pressure.后面还有好多 唉.求翻译 加一句 determine the empirical and molecular formula of a compound 答案 用普适气体定律方程式来决定用多少摩尔(mol,化学单位)气体,或者多少体积,温度和压力.决...
in a chemical equation on a macroscopic level. The Avogadro constant is named after an Italian scientist Amedeo Avogadro, who in 1811 was the first to realize that the volume of gas is proportional to the number of molecules or atoms. Moles of a substance can be used to find the number ...
Ideal gas equation for ‘n’ number of moles is given by 02:51 Select the WRONG statement. 03:21 In constant volume gas thermometer temperature is calibrated in terms ... 02:44 The numerical value of R is 02:53 A thin bulb containing air at normal pressure at 41 °C is sealed. The...
Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.A common request on this site is to convert grams to moles. To complete this ...
<p>To solve the problem of finding the work done by the gas during a reversible isothermal expansion, we can follow these steps:</p><p><strong>Step 1: Understand the Given Information</strong> - Number of moles of gas (n) = 2 moles - Temperature (T) = 30
The van der Waals equation for \(n\) moles of a gas is \((P+\dfrac {n^{2}a}{V^{2}})(V-nb)=nRT\) where \(P\) is the pressure, \(V\) is the volume, and T is the temperature of the gas. The constant \(R\) is the universal gas constant and \(a\) and \(b...
Solve the equation in Step 2 to find that there are 3.33 moles of H2O in 600 grams of H2O. References Stoichiometry How to calculate the molar masses of chemical compoundsCite This Article MLA Tyler, Judy. "How To Determine Moles In Chemistry" sciencing.com, https://www.sciencing.com/deter...
So the equation is: 2H2 + O2 -->2H2O We can still deduce the stoichiometry of this reaction even if we do not know the mass of oxygen that reacted. The ratio of hydrogen to water is 1 : 1. But there is only one atom of oxygen in a molecule of water – half the...
Substituting known quantities into the solved equation, we can calculate the number of moles of gas in the container: n=(210000Pa)(0.083m3)(8.31J/K/mol)(293.15K)≈7.2mol The beaker has 7.2 moles of gas in it. Example 2 A large vacuum chamber has a minuscule pressure of ...
The van der Waals equation for n moles of a gas is(P+(n^2a)/(v^2))(V-nb)=nRT where P is the pressure, V is the volume, and T is the temperature of the gas. The constant R is the universal gas constant and a and b are positive constants that are characteristic of a pa...
