Question

2. Calculate the molecular weight of NO2CO3.10h20 .​

Answer 1

SODIUM CARBONATE

Molecular Formula Na2CO3 or CNa2O3

Molecular Weight:- 286 grams.

Given that,

The compound is given by,

$Na_{2}CO_{3}.10H_{2}O$

We know that,

The mass of sodium = 23 gram

The mass of Carbon = 12 gram

The mass of Oxygen = 16 gram

The mass of Hydrogen = 1 gram

We need to calculate the unit of mass

Using formula of unit of mass

$Formula\ of\ unit\ mass=Na_{2}CO_{3}.10H_{2}O$

Put the value of mass,

$Formula\ of\ unit\ mass=23\times2+12+3\times16+10(2+16)$

$Formula\ of\ unit\ mass=286\ gm$

Hence, The unit of mass is 286 grams.
