Answer:
Explanation:
Hello,
In this case, given the concentration of the potassium phosphate, we can compute the concentration of potassium ions by noticing that in one mole of salt, three moles of potassium ions are present. Moreover, since the molar units (mol/L) are in terms of potassium phosphate we should apply the following mole-mole relationship:
Best regards.
Hydroxychloroquine cannot be made from grapefruit and lemon rinds.
Hydroxychloroquine is not a natural compound, rather it can only be synthesized from quinoline molecule in the laboratories.
During the synthesis of hydroxychloroquine, several sequential chemical reactions and purifications are done.
Hydroxychloroquine is used in the treatment of:
- malaria
- systemic lupus erythematosus,
- rheumatoid arthritis
But when grapefruit and lemon rinds are boiled in water, a natural chemical compound known as limonene is obtained.
Therefore, hydroxychloroquine cannot be made from grapefruit and lemon rinds,

The answer would be false:)

Find the number of moles
C = n / V
C(Concentration) = 0.30 moles / L
V ( Volume) = 2 L
n = ??
n = C * V
n = 0.30 mol / L * 2 L
n = 0.60 mol
Find the molar mass
2Na = 23 * 2 = 46 grams
1S = 32 * 1 = 32 grams
O4 = 16 * 4 = 64 grams
Total = 142 grams / mol
Find the mass
n = given mass / molar mass
n = 0.06 mol
molar Mass = 142 grams / mol
given mass = ???
given mass = molar mass * mols
given mass = 142 * 0.6
given mass = 85.2 grams.
85.2 are in a 2 L solution that has a concentration of 0.6 mol/L
