Explanation:
So first find out the moles. The percentage is out of 100 so just convert the percentage into mass by just changing the sign.
Ga = 55g/69.7 = 0.789 moles
F=45g/19 = 2.37 moles
Then divide by smallest value to find out the formula
Ga=0.789÷0.789= 1
F=2.37÷0.789 = 3
GaF3
hope this helps:)
M/V=D

Answer:
S. aureus strain is less infectious, but its alpha-toxin is highly-toxic.
Explanation:
Given data:
LD50 for S. aureus alpha toxin 0.45 \mu g/kg
ID50 for same mouse density found to be 200,000
From the data information given above Staphylococcus aureus was done on mice. The result show that LD50 is found to be 0.45\mu g/kg and ID50 found to be 200,000 on same mouse population
the result taken together mean that S. aureus strain is less infectious, but its alpha-toxin is highly-toxic.
