Question

***BRAINLIEST ASNWERRR***How many grams are in 34.2 moles of Lithium (Li)?​

Answer 1

Mass of Li = 237.38 g

Further explanation

The mole itself is the number of particles contained in a substance amounting to 6.02.10²³  

$\large {\boxed {\boxed {\bold {mol = \frac {mass} {molar \: mass}}}}$

Known

Moles of Li = 34.2

Molar mass(MW) of Li = 6.941 g/mol

then mass of Lithium (Li) :

$\tt mol=\dfrac{mass}{MW}\\\\mass=mol\times MW\\\\mass=34.2\times 6,941~g/mol\\\\mass=\boxed{\bold{237.38~g}}$
