How many molecules are in 100. l of potassium hydroxide solution at stp?

Answer : There are in 100 Lof potassium hydroxide(KOH) solution at stp.

Explanation : To calculate the molecules we first need to find out the moles.

One mole of an ideal gas will occupy a volume of 22.4 liters at STP (Standard Temperature and Pressure, 0°C and one atmosphere pressure).

1 mole = 22.4 L

100 L =

100 L =

100 L = 4.46 mole potassium hydroxide(KOH)

Now , we need to convert 4.46 mole to molecules of KOH.

4.46 moles =

4.46 moles =

4.46 moles =

There are in 100 Lof potassium hydroxide(KOH) solution at STP.

i need mutiple choices

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
