Identify any calculations that will help you find the intermediate quantities. For example, to find the volume of the swimming pool, you need to know the approximate length, width and depth of the swimming pool. Identify anything that relates the intermediate quantities to the desired final quanti...
When you know moles of solute, you can work out molarity (M), the concentration of a solution expressed as the number of moles of solute per liter of solution. To work out molarity, you need to know the total volume of solution as well as the number of moles of solute. Divide the ...

2. A lab technician has 2 mol of X in an Erlenmeyer flask and pours in 1 liter of water in order to make a 2 M solution. Why is the solution not exactly 2 M? They did not account for the volume of the 2 moles of X so the solution is not 2 M. ...

Our human body is made up of approximately one hundred trillion cells. So, the overall number of human cells on the Earth is about 100×1012*6×109=6×1023. That corresponds to one mole. Let’s assume that the volume of one grain of sand is about 10-12 m3, while the area of the...
conversion from a large measurement quantity like liters to a unit of measurement used to measure a smaller quantity like milliliters, the answer should always be a larger number. It is important to ensure the correct unit of measurement is specified with the answer to prevent any ...
Answer to: How do you find the number of moles of a gas if the pressure is 1.00 atm, the volume is 800 L, the temperature is 325 K, and KE = 4.05...
Re: How to i convert g/mol to mol% g/dm3 mg/ml « Reply #14 on: November 17, 2011, 07:44:53 PM » Yeah exactly, you need the units in moles first, 0.053 mmol = 0.000053 mol. Then you multiply by the molar mass to get 0.01908 g of the substance. Logged Print...
All I have for data is the volume of unknown solution used. My lab is also asking me for the moles of Cu (2+). How would I get that?I don't have any masses (grams)!!! I don't even have the molarity so how do I get the moles??
