the average adult human male has a total blood volume of 5.0 L. if the concentration of sodium ion in this average individual is 0.135 M, what is the mass of sodium ion circulating in the blood

5.0L x 0.125M = ? mols Na^+

g = mols Na x atomic mass Na

16g na+ (aq)

Well, you know what they say, blood is definitely not made of chocolate pudding, but let's do some calculations anyways!

To find the mass of sodium ions circulating in the blood, we need to first calculate the number of moles of sodium ions present and then multiply it by the molar mass of sodium (22.99 g/mol).

Given that the concentration of sodium ions is 0.135 M and the total blood volume is 5.0 L, we can use the formula:

Moles of Sodium ions = Concentration × Volume

Moles of Sodium ions = 0.135 mol/L × 5.0 L

Moles of Sodium ions = 0.675 mol

Now, we just need to multiply the number of moles by the molar mass of sodium to find the mass:

Mass of Sodium ions = Moles of Sodium ions × Molar mass of Sodium

Mass of Sodium ions = 0.675 mol × 22.99 g/mol

Mass of Sodium ions = 15.51 g

So, the mass of sodium ions circulating in the blood would be approximately 15.51 grams. But don't worry, your blood won't start tasting like a salty snack anytime soon.

To calculate the mass of sodium ion circulating in the blood, we need to know the total blood volume and the concentration of sodium ion.

Given:
Total blood volume (V) = 5.0 L
Concentration of sodium ion (C) = 0.135 M

Step 1: Convert the blood volume to milliliters (mL)
1 L = 1000 mL
So, 5.0 L = 5.0 x 1000 = 5000 mL

Step 2: Calculate the number of moles of sodium ion
To do this, we need to multiply the concentration by the volume.
Number of moles (n) = C x V
n = 0.135 M x 5000 mL

Note: It is important to ensure that the units are consistent. We convert 5000 mL to liters by dividing by 1000.
n = 0.135 M x 5.0 L

Step 3: Calculate the mass of sodium ion
We will use the molar mass of sodium ion (Na+) to convert moles to grams. The molar mass of sodium ion is approximately 22.99 g/mol.

Mass (m) = n x Molar mass
m = (0.135 M x 5.0 L) x 22.99 g/mol

Step 4: Simplify the expression
m = 9.72375 g

Rounding to an appropriate number of significant figures, the mass of sodium ion circulating in the blood is approximately 9.72 grams.
