Molarity is a way of expressing concentration that is equal to the ratio of the moles of the solute to the liters of solution. The amount of substance in moles can be calculated through,
moles = (molarity) x (volume in liters)
Substituting the values,
moles = (0.135 M) x (5.0 L) = 0.675 moles
Multiply this value with the molar mass of sodium ion,
mass = (0.675 moles) x (23 g/ mole) = 15.525 grams
Therefore, the mass of sodium ion in the blood is 15.525 grams.
Answer:
Explanation:
For work to be done, force must be applied to move an object in the direction of the applied force.
Work is the product of force and distance. Workdone describes a change of energy between places.
If we apply force to a body without moving it through a distance, no work is done.
Work is only done when force is applied to move or displace a body.
If we only apply force and no movement occurs, no work is done..
The unit of force is Joules.
MZn: 65 g/mol
mZnCl₂: 65g+35,5g×2 = 136 g/mol
.....................
Zn + 2HCl -----> ZnCl₂ + H₂
65g.......................136g............
65g Zn ---- 136g ZnCl₂
3,57g Zn ---- X
X = (3,57×136)/65
X = 7,47g ZnCl₂
<span>A polymer is made of more monomers
Amino acid is a monomer.
When you have more amino acids, it's a polymer (a protein)
So the answer is amino acid
the other 3 are polymers</span>
Communities is all the populations living in an ecosystem at the same time. A predator-prey relationship is an organism that eats another organism.
