Answer:
2.00 g of ethanol
Explanation:
The density of the mixture is the total mass (ethanol + chloroform) divided by the total volume. Let's call the mass of ethanol as x, the volume of it as V1, and the volume of chloroform as V2.
V2 = mass of chlorofrom/density
V2 = 5/1.5 = 3.33
x = density*volume
x = 0.8*V1
The density of the mixture will be:
(x + 5)/(V1 + V2) = 1.2
(0.8*V1 + 5)/(V1 + 5/1.5) = 1.2
0.8V1 + 5 = 1.2V1 + 4
0.4V1 = 1
V1 = 2.5 cm³
x = 0.8*2.5
x = 2.00 g
Yes. You should probably get it fixed
Answer:NSAIDs work on a chemical level. They block the effects of special enzymes -- specifically Cox-1 and Cox-2 enzymes. These enzymes play a key role in making prostaglandins. By blocking the Cox enzymes, NSAIDs stop your body from making as many prostaglandins.
