Answer:

0.19g/mL

Step-by-step explanation:

The concentration of a solution is how much of a substance in in another substance, usually the amount of solute in a solvent.

The solute is the active ingredient powder. The solvent is the NS solution.

Divide the solute by the solvent.

75g ÷ 400mL

= 75g/400mL     Simplify for solute per one unit, 1 mL. Divide top by bottom.

= 0.1875g/mL   Round to the nearest hundredth, second decimal place.

≈ 0.19g/mL

Therefore the final concentration is 0.19g/mL.

Answer:

0.19 g/mL

Step-by-step explanation:

The concentration of the final solution is the ratio of the mass of the powder to the volume of the solution. It may be measured in g/mL.

The final concentration

= 75/400

= 0.1875  g/mL

≈ 0.19 to the nearest hundredths

Ann [662]

Answer:

Both angles x and y are 69 degrees

Step-by-step explanation:

Because the angle with measure 69 degrees and angle x are alternate interior angles, they have equal value. Therefore, x has measure 69 degrees. Because this figure is a trapezoid, angle y is supplementary to the angle with measure 111 degrees. Therefore, y=180-111=69 degrees as well. Hope this helps!
