How many moles of helium gas are contained in a 4.0 L flask at STP
Ratling [72]
First, you convert liters to moles. 
Usually you have to go to grams but this is STP.

Get moles directly by dividing the 4 by STP (22.4)
\frac{4}{22.4} =0.17857142857
About 1.8*10^{-1} or 0.18 moles whichever your teacher prefers

HELP Which of the following fractions can be used in the conversion of 32 m3 to the unit mm3?
poizon [28]
We know that each millimeter contains 10⁻³ meters. Writing this as a ratio:
1 mm : 10⁻³ m

We require a conversion from m³ to mm³, so we must take the cube of the ratio we have made:
1 mm³ = (10⁻³)³ m³

Therefore, the conversion used will be:
(1 mm / 10⁻³ m)³

When we multiply by this conversion, we will get:
32 m³ = 32 x 10⁹ mm³
