Answer:
The formula for lithium acetate is CH3COOLi
Explanation:
The formula for lithium acetate is obtained by replacing the hydrogen atom bonding to the oxygen atom in acetic acid with Li as shown below:
CH3COOH + LiOH —> CH3COOLi + H2O
Use the atomic mass of potassium, k, 39.1 g/mol, and the formula n = mass / atomic-mass.
Where n is the number of moles.
n = 250.0 g / 39.1 g/mol = 6.3939 mol.
Now multiply by Avogadro number to find the number of atoms:
6.3939 mol * 6.02*1023 atoms/mol = 38.49 * 10^23 atoms = 3.849 * 10^24.
Answer: 3.85*10^24

Explanation:
,
Answer: 43.2 grams
Explanation:
Given that,
Amount of moles of NH4 (n) = 2.4
Mass of NH4 in grams (m) = ?
For molar mass of NH4, use the molar masses of:
Nitrogen, N = 14g;
Hydrogen, H = 1g
NH4 = 14g + (1g x 4)
= 14g + 4g
= 18g/mol
Since, amount of moles = mass in grams / molar mass
2.4 mole = m / 18g/mol
m = 2.4 mole x 18g/mol
m = 43.2g
Thus, there are 43.2 grams in 2.4 moles of NH4.
The answer is conduction because that is A
