Answer to Question #6516 in Biochemistry for lindsey
Plasma is the fluid portion of blood. The concentratio of asprin ( molar mass= 180.0g/mol) in your plasma is found to be 2.99x 10-4 M after you take 2 tablets of asprin. If the volume of your plasma is 5.85 L, how many grams of aspirin are in your blood? ( assume density of plasma is 1.00g/mol.)
V=5.85 L C=2.99x 10-4 M
2.99x10-4 moles in 1 litre X moles & & & & & in 5.85 L
X=(2.99x10-4* 5.85)/ 1= 1.749x10-3 m=n*Mm=1.749x10-3 * 180.0=0.3148 m=0,3148 g
I’ve used Assignment Expert twice now, and I’m a full fledged fan. This morning I had a crunching 7 hour deadline for a huge programming assignment I forgot was due, and turned to them for help. The estimate was affordable and easy to pay for through PayPal. Shortly after, an expert got to work on the problem at hand. The operator was in constant contact with me throughout the entire process, and everything went quickly and smoothly. After looking through the assignment, I was happy to find that everything ran very smoothly, and no shortcuts were taken/no requirements were omitted. I wish I could say more about this service. It’s truly a game changer and has saved my back more than once now.
