Question

calclute the number of mole of magnesium present in a magnesium ribbon weighing 12gram. molar atomic mass of mg is 24 mole​

Answer 1

$\Large\underline{\underline{\sf Given:}}$

• Mass of Magnesium ribbon = 12g

• Molecular Mass of Magnesium=24 mole

$\Large\underline{\underline{\sf To\:Find:}}$

• Number of moles of Magnesium

$\Large\underline{\underline{\sf Formula\:Used:}}$

$\large{\boxed{\boxed{\sf \pink{Mole=\dfrac{Mass}{Molecular\:Mass}}}}}$

$\Large\underline{\underline{\sf Solution:}}$

$\Large{\sf Mole=\dfrac{Mass}{Molecular\:Mass}}$

$\implies{\sf Mole=\dfrac{12}{24}}$

$\implies{\sf Mole=\dfrac{1}{2}}$

$\implies{\sf Mole=0.5\:mole }$

$\Large\underline{\underline{\sf Answer:}}$

•°• Number of moles of Magnesium is 0.5 moles

Answer 2

Answer:

$0.5 \: moles$
