Answer:
Avogadro's number or Avogardro’s constant
Explanation:
I’m pretty sure this is correct if it’s not I’m sorry lol.
The amount of force is what this is for
Answer:
0.6257 M is the molarity of solution that is 5.50 percentage by mass oxalic acid.
Explanation:
Mass percentage of oxalic acid = 5.50%
This means that in 100 grams of solution there are 5.50 grams of oxalic acid.
Mass of solution , m = 100
Volume of the solution = V
Density of the solution = d = 1.024 g/mL
![V=\frac{m}{d}=\frac{100 g}{1.024 g/mL}=97.66mL](https://tex.z-dn.net/?f=V%3D%5Cfrac%7Bm%7D%7Bd%7D%3D%5Cfrac%7B100%20g%7D%7B1.024%20g%2FmL%7D%3D97.66mL)
V = 97.66 mL = 0.09766 L
(1 mL = 0.001 L)
Moles of oxalic acid = ![\frac{5.50 g}{90 g/mol}=0.06111 mol](https://tex.z-dn.net/?f=%5Cfrac%7B5.50%20g%7D%7B90%20g%2Fmol%7D%3D0.06111%20mol)
![Molarity=\frac{\text{Moles of solute}}{\text{Volume of solution in L}}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20solute%7D%7D%7B%5Ctext%7BVolume%20of%20solution%20in%20L%7D%7D)
The molarity of the solution :
![=\frac{0.06111 mol}{0.09766 L}=0.6257M](https://tex.z-dn.net/?f=%3D%5Cfrac%7B0.06111%20mol%7D%7B0.09766%20%20L%7D%3D0.6257M)
0.6257 M is the molarity of solution that is 5.50 percentage by mass oxalic acid.
Answer: Each ion, or atom, has a particular mass; similarly, each mole of a given pure substance also has a definite mass. The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol).
Explanation:
Answer:
Clouds are not made of liquid water but they hold liquid water, and when the pool of liquid water that fills the inside of clouds gets too large for the cloud to hold, the cloud releases the water as rain. ... Rain does not fall from clouds.
