To solve, you find the correct mole ratio from the given equation. The questions asks for how many moles of H2O from 2.0 moles of NH3(ammonia), so the mole ration is going to be 6:4.
6 moles of  H2O and 4 moles of NH3.

<u>Tip:</u>
We multiply the given with what we want divided by what we want to get rid of.

So, 2.0mol NH3 x 6mol H2O /4mol NH3.


The answer is  3 moles of H2O or 3mol H2O

Answer : The number of moles of H_2O formed is, 3 moles

Solution : Given,

Moles of NH_3 = 2.0 moles

Now we have to calculate the moles of H_2O

The given balanced chemical reaction is,

4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(g)

From the balanced reaction, we conclude that

As, 4 moles of NH_3 react to give 6 moles of H_2O

So, 2.0 moles of NH_3 react to give \frac{6}{4}\times 2.0=3 moles of H_2O

Therefore, the number of moles of H_2O formed is, 3 moles

The density of copper is 8.94 g/cm3. An irregular shaped sample of metal is 14 g and displaces a volume of 2.98 mL. (a) Find the
Vedmedyk [2.9K]

Explanation:

<h2>(a).</h2>

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of metal = 14 g

volume = 2.98 mL = 2.98 cm³

It's density is

density =  \frac{14}{2.98}  \\  = 4.69798657...

We have the answer as

4.70 g/cm³

<h2>(b).</h2>

The metal is not copper since it's density is less than that of copper.

Hope this helps you
