Question

Calculate the molarity of sodium carbonate,2.62of which are dissolved in 600 ml of solution​

Answer 1

Answer:

NaCo³(molar mass...83gmol')

mole..2.63g/83gmol'

..1.031mol

(m)..1.031/600ml..0.0017molml'

0.0017molml'/1000mll'..1.7molL

Answer 2

Explanation:

the molar mass of Na2CO3 = 23*2 +12+16*3

= 46+12+48

= 106gmol

Now, = 2.62g/ 106gmol

= 0.024 mol

we know that,

M= no. of moles of solute/volume of the solution in litre

= 0.024 mol * 1000 mL/ 600 mL

= 0.04 moL L
