Answer:
= 1.806 × 10^25 molecules.
Explanation:
1 mole of CO2 contains 6.02 × 10^23 molecules
30 moles of CO2 will contain ( 30 × 6.02 × 10^23 )
= 1.806 × 10^25 molecules.
Answer:
90.37 g
Explanation:
From Avogadro Number,
1 mole of every substance contains a particle number of 6.02×10²³
From the question,
1 mole of CH₄ contains 6.02×10²³ molecules.
But,
1 mole of CH₄ has a mass of 16 g
Therefore,
16 g of CH₄ contains 6.02×10²³ molecules
Then,
Y g will contain 3.4×10²⁴ molecules
Solve for Y
Y = (16× 3.4×10²⁴)/(6.02×10²³)
Y = 90.37 g
