Hey User!!
Here's your answer.

• Question :
Mass of 0.1 mole of KNO3 = ?

• Answer :
Number of moles = 0.1 mole
• Molar mass of KNO3,
=> 1*39.09 + 1*14 + 3*16
=> 101.10 g/mol

Now, Number of moles, n = mass/Molar mass

$= > 0.1 = m \div 101.10$
$= > m = 0.1 \times 101.0 = 10.10$

Therefore, mass of 0.1 mole of KNO3 is 10.10 g.

Hope it helps!!
