a solution has a density of 1.50 g/mL. how many grams are needed to obtain 10.0 mL of solution?
look at the units!
1.50 g/mL = (x g)/(10.0mL)
find x.

To determine the number of grams needed to obtain 10.0 mL of solution, we can use the concept of density. The formula for density is:
Density = Mass / Volume
In this case, we are given the density (1.50 g/mL) and the volume (10.0 mL), and we need to find the mass.
Rearranging the formula, we get:
Mass = Density * Volume
Substituting the given values:
Mass = 1.50 g/mL * 10.0 mL
Mass = 15.0 grams
Therefore, you would need 15.0 grams of the solution to obtain 10.0 mL.
