Question

Find the mass present in 85 mile of sodium carbonate mole​

Answer 1

Answer:

I think the compound is Na2CO3

Given number of moles = 0.85 moles

Molar mass of Na2CO3 = ( 2 x 23 ) + ( 1 x 12 ) + ( 3 x 16 )

= 106 gmol-1

Number of moles = mass / molar mass

So, Mass = Number of moles x Molar mass

= 0.85 moles x 106 gmol-1

= 90.1 g

Therefore mass of Na2CO3 is 90.1 g
