Question

what is mass of

0.6 mole of na2co3​

Answer 1

$\huge{\bf{\underline{\underline{Solution:-}}}}$

Molar mass of Na2CO3 = (23 × 2) + 12 + (16 × 3) = 106g.

Thus 1 mole of Na2CO3 weights 106g.

Number of mole given = 0.6

So,

Mass of the sample = number of moles × molar mass

= 0.6 × 106

= 63.6g

Hence, the mass of 0.6 moles of Na2CO3 is 63.6g.

Answer 2

$\huge{\underline{\underline{\mathbf{Answer: -}}}}$

$63.6gram$

$\huge{\underline{\underline{\mathbf{Explanation: -}}}}$

✍.. Molar mass of

$na_{2} co_{3} is = > (23 \times 2) + 12 + (16 \times 3)$

$= > 106gram$

given that,

no. of moles = 0.6mole

we know that,

$mole = \frac{mass}{molecular \: weight}$

$= > 0.6 = \frac{mass}{106}$

$= > 106 \times 0.6 = mass$

$= > 63.6gram$
