Answer : The moles of potassium is
Explanation : Given,
Mass of potassium = 40 mg = 0.04 g
conversion used : 1 mg = 0.001 g
Molar mass of potassium = 39 g/mol
Now we have to calculate the moles of potassium.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the moles of potassium is
Answer:
8,5 E10 nm
Explanation:
⇒ 0.85 E-2 Km * ( 1000 m / Km ) * ( 1 E9 nm / m ) = 8.5 E10 nm
⇒ 0.85 E-2 Km = 8.5 E10 nm
