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:
The perimeter of the square would be 40x
Step-by-step explanation:
In order to find that, we can use the equation for the length of a perimeter in a square.
P = 4s
Now we can input the value of the sides for s
P = 4(10x)
P = 40x
230 + the sales tax (6%) = Total payed
230 times 0.06 = 13.8 dollars
230 + 13.8 = $243.8
