Question

calculate the formula unit of mass of na2co3*10h2O

Answer 1

Hii friends solution of this question is very simple only the things which you should know are:

Mass of Sodium=23grams

Mass of Carbon=12grams

Mass of Oxygen=16grams

Mass of Hydrogen=1gram

So, there is your solution:

Formula unit mass=Na2Co3.10H2O

=23×2+12+16×3+10(2+16)

=46+60+180

=286grams.

Answer 2

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.
