Determine the mass of 5.2 x 10 power of 21 molecules of propanol c3h7oh(l), on grams.

where the Avogadro's constant that relates the number of particles to their number, in the unit moles .

The molar mass of propanol- mass per mole propanol- can be directly deduced from its molecular formula with reference to a modern periodic table.

of propanol molecules would thus have a mass of

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck
