Question

What is the mass of 5 miles in ba3n2

Answer 1

Answer:

2200 g

Explanation:

Data Given:

no. of moles of Ba₃N₂ = 5 moles

mass of Ba₃N₂ = ?

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  Ba₃N₂

molar mass of  Ba₃N₂ = 3(137.3) + 2(14)

molar mass of  Ba₃N₂ = 412 + 28

molar mass of  Ba₃N₂ = 440 g/mol

Put values in equation 1

         mass in grams = 5 moles x 440 g/mol

         mass in grams = 2200 g

So,

mass of Ba₃N₂ = 2200 g
