Question

MASS of sodium in 53 g of sodium bicarbonate

Answer 1

Explanation:

Sodium carbonate Na2CO3

Molecular weight = 106g/mole.

There in 53g there are 53/106 gms of Na2CO3 = 0.5 moles

By the formula there are 2 moles of Na for every mole of Na2Co3

Therefore there is 2*0.5 moles on Na = 1 mole Na

Molecular weight of Na = 23g/mole

Therefore should be 23g Na in 53g Na2CO3 mark me brainliest answer
