Mass of Li = 237.38 g
<h3>Further explanation</h3>
The mole itself is the number of particles contained in a substance amounting to 6.02.10²³
<h3>Known</h3>
Moles of Li = 34.2
Molar mass(MW) of Li = 6.941 g/mol
then mass of Lithium (Li) :
Answer:
Explanation:
pressure of dry nitrogen gas at 20° = Partial pressure of nitrogen and partial pressure of water at that temperature .
The pressure of dry nitrogen gas= total pressure - vapour pressure of water at 20°C
= 200 k Pa - 2.34 k Pa
= 197.66 kPa.
