Chemists routinely perform calculations of the amount of substances necessary to carry out a chemical reaction. Textbooks refer to this topic as "stoichiometry." Chemists base all stoichiometric calculations on moles. A mole represents 6.022 x 10^23 for
Answer to: Explain how to find the molar mass of argon. By signing up, you'll get thousands of step-by-step solutions to your homework questions...
Step 1: Make a list of the pressure, volume, and temperature of the gas, converting it to SI units if necessary. Step 2: Use the ideal gas law to calculate the number of moles of the sample. What is the Ideal Gas Law? Ideal Gas Law: The ideal gas law is the mathema...
Determine the number of moles of gas in the vessel. Homework Equations 1 mol= 6.03 x 10^23 # of moles= mass of the gas/molecular mass The Attempt at a Solution I converted Liters to grams, which would make it 7,710 grams, but I'm not sure how to find the molecul...
How do you find the molar mass of a compound that weighs 0.375 g and has 0.00468 moles? How to find moles of unknown solid acid? Suppose the mass of one mole of a substance is 45.0 g. How many moles of the substance is present in 0.568 g of the sample?
To find the molar mass of NaCl, you add the mass of each element. Work out 22.9898 + 35.4530 = 58.4538.Moles of Solute Say you create a solution with 200 grams of table salt. One mole equals the molar mass of the solute which is 58.4538 grams. Divide the mass of the solute by the...
how many moles of gas?A gas with an initial temperature of 790 °C undergoes an isobaric process . Final temp = 81.3 CA) How many moles of gas are there? Hint:You must use Pascal for pressure and cubic meters for volume. The conversion to Pascal from atmospheres is easy: 1atm=101...
A coal miner standing on the back of a car in a mine tunnel in the early 1900s. Notice that the sides of the tunnel are shored up with timber. Public works tunnelscarry water, sewage or gas lines across great distances. The earliest tunnels were used to transport water to, and sewage...
<p>To find the number of moles of helium gas needed to achieve an internal energy of 100 Joules at a temperature of 300 K and a pressure of 1.00 atm, we can use the formula for the internal energy of a monatomic ideal gas. </p><p>1. <strong>Identify the
1 kg mole refers to 1000 moles of a substance. This is because "kg" means kilogram, and 1 mole is defined as the amount of substance that contains 6.022×1023 entities. Step 3: Calculate the number of molecules in 1 kg moleTo find the total number of molecules in 1 kg mole, we ...
