A solution has a density of 1.50 g/mL. How many grams are needed to obtain 10.0 mL of solution?
10 ml will have a mass of =density*volume=15grams
Answer is : 15 grams
1 mL = 1.50 gm
(1.50 x 10) = 15gm
A soultion has a density of 1.05 g/mL. How many grams are needed to obtain 14 mL of sloution?
To determine the number of grams needed to obtain 10.0 mL of solution, we can use the concept of density. Density is defined as mass per unit volume, so we can rearrange the equation to solve for mass.
The formula for density is:
density = mass / volume
Given that the density is 1.50 g/mL and the volume is 10.0 mL, we can substitute these values into the equation and solve for mass.
1.50 g/mL = mass / 10.0 mL
To isolate the mass, we can multiply both sides of the equation by 10.0 mL:
1.50 g/mL * 10.0 mL = mass
15.0 g = mass
Therefore, you would need 15.0 grams to obtain 10.0 mL of the solution.
