Answer:

The number of moles in 44g of NaOH = 1.1 moles

Explanation:

Gram molecular weight of NaOH= 23 + 16 + 1 = 40g

We use unitary method here;

1 mole of NaOH = 40g

? moles of NaOH = 44g

44/40 = 1.1 moles

44 GRAMS OF NaOH CONATINS 1.1 moles of NaOH.

Explanation:

  • Every mole of a substance contains 6.022*10^{23} atoms/molecules.
  • 1 mole of sodium hydroxide will also contains 6.022*10^{23} molecules and 40grams of NaOH.
  • To calculate the given moles of NaOH, we will first find its molar mass and then divide it by the given mass.
  • Molar mess of NaOH = Na+O+H=23+16+1=40g/mol.
  • Moles of NaOH = \frac{givenmass}{molar mass}=\frac{44}{40} =1.1
  • 44 grams of NaOH will contain 1.1 moles of NaOH.
