Answer:

K= 25.16%

Mn= 34.59%

O= 40.25%

Explanation:

KMnO_4

Find the total mass of the compound. You can do this by multiplying by the molar mass.

K=40*1=40\\Mn=55*1=55\\O=16*4=64

add them:

40+55+64=159g

Now convert each element individually to grams using molar mass

1molK(\frac{40gK}{1molK} )=40gK

1molMn(\frac{55gMn}{1molMn} )=55gMn

4molO(\frac{16gO}{1molO})=64gO

Divide by the mass of the compound and multiply by 100

K=\frac{40g}{159g} *100=25.16

Mn=\frac{55g}{159g}*100=34.59

O=\frac{64g}{159g}*100=40.25

How do you Convert 19mL to pL?
s2008m [1.1K]

Picoliter is a unit of measurement for liquids.

One picoliter = 1×10⁻⁹ mililiters

So:

19 mL ---- x pL

1×10⁻⁹ mL ---- 1 pL

1×10⁻⁹x = 19

x = 1,9 × 10¹⁰ pL

or 19,000,000,000 pL

Answer: 1.9 × 10¹⁰ pL
