Answer to Question #63928 in General Chemistry for naj

Question

What mass of solute is needed to make 80.5 mL of a 0.597 M solution?

Answer 1

What chemicals?

1. Use Concentration (C)/volume (V)= moles; in our case – 0,597/0,0805= 7,4161 moles
2. Use Moles =mass/ molar mass, rearrange it to find the mass:
Mass= moles * molar mass
In this case: moles= answer from 1.
Calculating Molar mass (substance)
And finally find mass of solute.
