Question

How many grams of nitric acid can be obtained from 4 mols of ammonia? pleaseee write answer quick

Answer 1

Дано:
n (NH3) = 4моль
m (HNO3) - ?

NH3 + 2O2 = HNO3 + H2O
n=1моль ⠀ ⠀ n=1моль
⠀ ⠀ ⠀ ⠀ ⠀ ⠀ М=63г/моль

1) n (HNO3) = n (NH3) = 4моль
2) m (HNO3) = 63*4 = 252г
Ответ: m (HNO3) = 252г

Answer 2

To find the number of grams of nitric acid that can be obtained from 4 moles of ammonia, we need to first understand the balanced chemical equation for the reaction between ammonia and nitric acid. The balanced chemical equation is as follows:

$NH_3 + HNO_3 \rightarrow NH_4NO_3$

From the balanced equation, we can see that 1 mole of ammonia reacts with 1 mole of nitric acid to produce 1 mole of ammonium nitrate. Therefore, if 1 mole of ammonia reacts to produce 1 mole of nitric acid, then 4 moles of ammonia will produce 4 moles of nitric acid.

The molar mass of nitric acid (HNO3) is approximately 63.01 g/mol.

Therefore, the number of grams of nitric acid obtained from 4 moles of ammonia would be:

$\text{Number of grams} = \text{Number of moles} \times \text{Molar mass}$ $\text{Number of grams} = 4 \text{ moles} \times 63.01 \text{ g/mol} = 252.04 \text{ grams}$

So, 4 moles of ammonia will produce 252.04 grams of nitric acid.
