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.
