Apatient needs 0.024 g of a sulfa drug. there are 12-mg tablets in stock. how many tablets should be given?

Answer : The number of tablets given should be, 0.5

Explanation :

We are given :

Mass of sulfa drug for a patient = 0.024 g

Total mass of tablets = 12 mg =

(Conversion factor: 1 g = 1000 mg)

To calculate the number of tablets, we divide the total mass of tablets to the mass of sulfa drug for a patient.

Putting values in above equation, we get:

Hence, the number of tablets given should be, 0.5

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
