Question

What would be the mass in grams of 1.204•10^24 molecules of sulfur dioxide

Answer 1

Answer:

128 amu

Explanation:

as 6.023×10`23 contain mass is 64 amu

then 12.046×10`23 contain 64×2 mass=128amu

Answer 2

Answer:

Explanation:

Given:

No of molecules = 1.202 * 10^24 molecules of SO2

To find out:

Mass of SO2 =?

Solution:

Formula being used here:

No of molecules = Given mass/molar mass * Avogadro's number

Molar mass of SO2= 64 g/mol

So,

Mass of SO2 = No of molecules * molar mass / Avogadro's number

Putting values:

Mass of SO2 = 1.204 * 10^24 * 64 / 6.02 * 10^23

Mass of SO2= 12.8 * 10^1

Mass of SO2=128 g

So,the mass of SO2 is 128 g/mol

HAVE A GREAT DAY MATE :)
