A spherical water tank holds 15000ft^3. What is the diameter of the tank? Use V=pie/6*d^3

1 answer:

3 0

$V=\frac{ \pi }{6d^3}\\\\
Substitute\ into\ formula\ V=15000ft^3\\\\
15000=\frac{ \pi }{6d^3}\ \ |*6d^3\\\\90000d^3= \pi \ \ |:90000\\\\
d^3=\frac{ \pi }{90000}\ \ \sqrt[3]{}\\\\
d\approx0,07ft \\\\Diamater\ is\ equal\ to\ 0,07ft.$

A student needed to prepare 500mL of 1X TAE buffer to run a QC gel. The stock solution in the lab is 5X TAE. What volumes of sto

Xelga [282]

Answer:

you need 100ml of 5X TAE and 400ml of water.

Step-by-step explanation:

You need to use a rule of three:

$C_1V_1=C_2V_2$

where:

$\left \{ {{C_1= 5X} \atop {C_2=1X}} \right.$

and

$\left \{ {{V_1 = V_{TAE}} \atop {V_2=500ml}} \right.$

Therefore:

$V_{TAE} = \frac{V_2*C_2}{C_1}$

$V_{TAE} = 100ml$

Then just rest the TAE volume to the final Volume and you get the amount of water that you need to reduce the concentration.
