Answer:
5.41 x 10²² g
Explanation:
Data Given:
no. of moles of sodium = 2.35 x 10²¹ moles
mass of sodium = ?
Solution:
Formula used
no. of moles = mass in grams / molar mass
To find mass rearrange the above equation:
mass in grams = no. of moles x molar mass. . . . . . (1)
- molar mass of Sodium (Na) = 23 g/mol
Put values in equation 1
mass in grams = 2.35 x 10²¹ moles x 23 g/mol
mass in grams = 5.41 x 10²² g
So,
mass of Sodium (Na) = 5.41 x 10²² g
