Answer : The diameter in meters is, 5.5\times 10^{-9}m

Explanation :

As we are given that the diameter of red blood cells is, 5.5 nm. Now we have to convert it into meter.

The conversion used from nanometer to meter is:

1nm=10^{-9}m

As, 1nm=10^{-9}m

So, 5.5nm=\frac{5.5nm}{1nm}\times 10^{-9}m=5.5\times 10^{-9}m

Thus, the diameter in meters is, 5.5\times 10^{-9}m

Rom4ik [11]

Answer:

Use the activity formula,  

T1/2 = 4.468 x 10^9 yr x 365 x 24 x 3600 = 1.409 x 10^17 sec  

l = ln(2)/T1/2 = ln(2)/1.409 x 10^17 = 4.91932697 x 10^-18 s-1  

DN/Dt = lN, 265 = 4.91932697 x 10^-18 x N  

<u><em>N = 5.38 x 10^19 nuclei</em></u>

determine the volume of your 0.25 m stock solution that is needed to make 200 ml of 0.010 m nacl. show all calculations
rusak2 [61]

The volume of your 0.25 m stock solution that is needed to make 200 ml of 0.010 m NaCl is <u>0.008 L</u>

Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.

Calculation:-

C₁ =  0.25 M

V₁ = ?

C₂ = 0.010 M

V₂ = 200 ml = 0.2 L

V₁ = C₂V₂/C₁

    = 0.010 ×  0.2 /  0.25

   =<u> 0.008 L</u>

The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of answer.

The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.
