How many moles are contained in 5.0 g of SO2:

Hey there!

Molar mass SO₂ = 64.066 g/mol

Therefore:

1 mole SO₂ 64.066 g

(moles SO₂ ) ?? 5.0 g

( moles SO₂) = 5.0 * 1 / 64.066

(moles SO₂) = 5.0 / 64.066

moles = 0.0780 moles of SO₂

Hope this helps!

the answer is b & c i believe : )

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
