Question

11. number of moles present in 575 g of Na? ​

Answer 1

Answer:-

• Mass of Na=575g
• Molar Mass of Na=23u

We know

$\boxed{\sf ☆Number\:of\:moles=\dfrac{Mass}{Molar\:Mass}}$

$\\ \sf\longmapsto Number\:of\:moles\:of\:Na=\dfrac{575}{23}$

$\\ \sf\longmapsto Number\:of\:moles\:of\:Na=25mol$

25mol of Na is present in 575g of Na
