Question

what is the mass of 1.00 mol of sodium hydrogen carbonate?

Answer 1

Answer:

Explanation:

Summing up the atomic masses for 1 mol NaHCO3 , there are 22.99⋅g sodium + 1.008⋅g hydrogen + 3×16.00⋅g oxygen + 12.0⋅g carbon = 84.0⋅g⋅mol−1

Answer 2

The mass of 1.00 mol of sodium hydrogen carbonate is 84g.

Given:

1 mole of sodium hydrogen carbonate.

To Find:

The mass of 1.00 mol of sodium hydrogen carbonate.

Solution:

To find the mass of 1.00 mol of sodium hydrogen carbonate we will follow the following steps:

As we know,

The formula of sodium hydrogen carbonate = NaHCO₃

The formula unit mass of one mole of sodium hydrogen carbonate = sum of masses of all the atoms in the formula.

So,

$mass \: of \: sodium + \:mass \: of \: hydrogen + \:mass \: of \: carbon + 3 \: mass \: of \: oxygen$

$= 23 + 1 + 12 + 3 \times 16 = 46 + 12 + 48 = 84g {mole}^{ - 1}$

Henceforth, the mass of 1.00 mol of sodium hydrogen carbonate is 84g.
