7 0

Molar mass of NaHCO_3

  • 23+1+12+3(16)
  • 36+48
  • 84g/mol

Now

\\ \sf\longrightarrow No\:of\:moles=\dfrac{Given\:mass}{Molar\:mass}

\\ \sf\longrightarrow No\:of\; moles=\dfrac{2.61}{84}

\\ \sf\longrightarrow No\:of\:moles=0.0312mol

How many molecules are in 100 g of C6H120,?*​
Grace [21]

Answer:

3.37 × 10²³ molecules

Explanation:

Given data:

Mass of C₆H₁₂O₆ = 100 g

Number of molecules = ?

Solution:

Number of moles of C₆H₁₂O₆:

Number of moles = mass/molar mass

Number of moles = 100 g/ 180.16 g/mol

Number of moles = 0.56 mol

Number of molecules:

1 mole contain 6.022 × 10²³ molecules

0.56 mol × 6.022 × 10²³ molecules /1 mol

3.37 × 10²³ molecules
