Well, your not alone! ( : I was going to post the steps before but i thought it would be to much. But, I'm post them so you can have a look see...Line 16 through 18 get to the heart of what i need to find. Trying to find what volume to multiple by is a bit tricky too. Mixed and diluted the...

Hi tiny-tim Thanks for the mu: µ, Let me see if I understand this correctly. if the acid enzyme is 1.022 times the pure enzyme concentration of 1mg/mL, that would give 1.022 x 1mg/mL = 1.022 mg/mL correct? I believe the steeper the slope for the extract indicates that I extracted more...

Maybe if i show you what i did it might help. Extraction and Quantification of Acid Phosphatase Enzyme from Wheat Germ 1. Obtain a 15 mL conical centrifugation tube and add 0.5 grams of raw wheat germ to the tube. 2. Add 5 mL of 0.05M Sodium Acetate buffer, pH 4.5. Cap and shake the...

The pure anzyme was given at a 1mg/mL concentration. … The question is: How much (ug) of acid phosphatase enzyme was extracted from the wheat germ? I believe the 1.022 is in (mg/mL). Dont I need to multiply this by a volume to get to a mass? Or is this the mass?

Thanks for taking a look!

Homework Statement Hello, I'm creating a Michealis/Menten curve and need to find the X values for the graph. Homework Equations These are the instructions given to find the X values: To obtain the X value, plot the molar concentration (molarity) of substrate used in each well...

Homework Statement The lenses are separated by 250mm. Where should the object be places so that the final image is formed at infinity? I'm confused.

One more thing...This might be a stupid question. But once you've found I1 and I2. If one of those is a negative number...it indicates that the current is flowing in the other direction. So, if I3 = I1 + I2 and let’s say that I1=-1, and I2 = 1would that change the equation to I3= I1-I2 giving...

Oh yeah...i see it now. Thanks!

I3 is 2A, but i don't see the I1-I2 in this situation. Arnt I1 and I2 both converving onto I3? Or I am I looking at it wrong?

Sorry, typed that in wrong...I've got -1A for I2, 1A for I1 and 0? for I3.

I've got -1A for I1, 1A for I2 and 2A for I3

Yes, I believe i do. Let me take a stab at it and see what trouble i can get into...

I'm not sure what to do when i hit a battery. I know that you assign a positive value to the battery if the battery output follows the tracing direction. But, for some reason it doesn't always work out. Like you see in this problem...

Well, I use whatever gets me there...But, the short line is negative.
