Question

what is the mass of 5 moles of NaOH .​

Answer 1

Answer:

Hiii...

As we know,

No of moles = Given mass/molecular mass

So here....

5 = x/40

x = 200 grams...

Hope this helps...☺☺❤❤

Answer 2

Given: 5 mol of NaOH.

To find: We have to find the mass.

Solution:

The formula of sodium hydroxide is NaOH.

The atomic mass of the Na atom is 23 and the H atom is 1.

The atomic mass of the Oxygen atom is 16.

Thus, the molecular mass of NaOH is 23+16+1=40u.

We know that 1 mole of sodium hydroxide has a molecular mass of 40u.

5 moles of sodium hydroxide will contain-

$5 \times 40 = 200$

The mass of 5 moles of NaOH is 200u.
