Answer:
6.02×10²³ particles / 1 mol
Explanation:
In this question the choices are missed.
For determine the particles of Na, in 0.25 moles we should know that the mole referrs to the Avogadro's number.
1 mol of anything contains 6.02×10²³ entities, that's why we should apply this conversion factor to find the final answer:
0.25 mol . 6.02×10²³ particles / 1 mol = 1.50×10²³ particles
In conclussion: 1.50×10²³ particles of Na are contained in 0.25 moles of Na
Answer:
NAD (Nicotinamide adenine dinucleotide)
Explanation:
NAD+ (or NADH in its reduced form) is important in cellular respiration as it acts as an electron carrier, providing a shuttle system for the movement of electrons. This drives a proton pump and generates ATP via oxidative phosphorylation. Niacin is a form of vitamin B3 that we get from our diet and is a precursor for NAD.
Answer:
Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.
