Answer:

Henry Moseley.

Explanation:

Hello,

Henry Moseley's work stated that it is better to organize the periodic table in the light of the atomic number (which accounts for the amount of protons and electrons) instead of the atomic mass, because atomic numbers are not arbitrarily assigned as long as they have the aforesaid physical basis.

Best regards.

mel-nik [20]

Answer:

0.007 g of deprenyl dose is required fro the patient with body mass of 70 kilograms.

Explanation:

The dose for treating Parkinson’s disease = 100 μg/kg body weight

Mass of patient's body = 70 kg

Amount of dose of deprenyl required = 100 μg/kg × 70 kg = 7,000 μg

1 μg = 0.00001 g

7,000 μg = 7,000 × 0.000001 g = 0.007 g

0.007 g of deprenyl dose is required fro the patient with body mass of 70 kilograms.
