Homework Statement without posting all the lab data I am just wondering if this makes sense. I calculated moles Chlorine to moles Copper as 2:1. (seems reasonable to me). Then I calculated mole ratio of water to Copper in hydrated sample as 20:1. (not sure if this is "reasonable " ...
A kilogram of water takes up a liter of volume, so if the moles weigh \( 4.52\times10^{22} \) kilograms, they take up about \( 4.52\times10^{22} \) liters of volume. You might notice that we’re ignoring the pockets of space between the moles. In a moment, you’ll see why...
How to Convert Liters to Moles for Liquids Many substances are dissolved in water or other solvents in a laboratory for later use in reactions. These solutions are typically described as “molar solutions.” For example, if you dissolve 1 mol of salt (NaCl) in 1 L of water (H2O), you...

You can also find the total number of molecules (or atoms) in the Number of molecules / atoms field. How to convert grams to moles: an example Take a look at the example of how to calculate moles from grams. Imagine you have 6 liters of pure water: Find the molar mass of a ...
We can find the moola mass of a compound or an element from the molecular formula. To find the molar mass, we have to add the molar mass of each atom present in the molecule.Answer and Explanation: We have the following given data {eq}\begin{align} ~\text{ Mass of water is} ~m...
How do you find the osmolarity of 4.2 grams of sucrose (table sugar) in 100 g of water? What mass of copper(II) nitrate, Cu(NO_3)_2, must be decomposed to produce 1500 g of copper(II) oxide, CuO? How many liters of N2 are required to react completely with 8.5 g of Al? 2Al...
5) ok saline is a 0.9% (g/100ml) (which is just like saying for every 100mL of water you need 0.9g of salt). The question asked you for 2 liters of saline (2000mL). do you get it? Although this logic seems like a proportion problem you should practice using dimentional analysis...
