Say you need to make a solution of 1M NaCl for a reaction you are running. How would you know how much salt to weigh out and then add to a given volume of water? To do this, you need to find a way to relate the
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...
This is because atoms react with each other in known proportions in a way unrelated to atomic mass. One mole (1 mol) of anything is 6.02 × 1023 particles; 1 mol in a volume of 1 L has a molarity of 1.0. Thus 6 mol of NaCl in 8 L of aqueous solution has a molarity of 6 mol...
While the remaining solid CaCl_2 is filtered out of the solution and found to have a mass of 5.509g. What is You have a 250 mL solution of 0.13 M calcium iodate. How many grams of potassium iodate need to be added to the solution to begin...
In other words, how many milligrams of the salt would you need to weigh out and add to a liter of solution? First, begin by converting millimolar to molar: (10 mmol MgCl2/1 L)x(1 mol/1000 mmol) = 0.010 mol MgCl2/1 L. Next, you can use the molar mass to find how many grams ...
Twenty锕昬ven EG based homopolymers were synthesized and three parameters, the molar mass (MM), the number of the ethylene glycol groups in the monomer, and the chemistry of the functional side group were varied to investigate how these affect their thermoresponsive behavior. The targeted MMs of...
We get this relation in terms of moles with the help of the balanced chemical reaction. We can convert the moles to grams by using the below formula : Number of moles=MassMolar massAnswer and Explanation: We are given the followin...
The ability of a restriction enzyme to find a single site by linear diffusion in the supercoiled plasmid is also presumed to be different than for any of the sites on a linear substrate. Although it is not common, some enzymes exhibit differences in their ability to cut supercoiled DNA ...
Find the number of moles of solute dissolved in solution, Find the volume ofsolutionin liters, and Divide moles solute by liters solution. Make certain to use the correct number of significant figures when reporting your answer. One easy way to track the number of significant digits is to ...
How do you calculate molecular mass and formula mass? How to find the molar mass of a compound? Make use of the chemical formula to determine the number of atoms of each element in the compound. Multiply the atomic weight of each element with its number of atoms present in the compound....
