9.98 g of NH₃ reacts with 23.4 g of O₂ (up to 3 significant figure).

<h3>What is Significant figures ?</h3>

The digits of a number that are used to express it to the required degree of accuracy, starting from the first non-zero digit.

The given chemical equation ;

4NH₃ + 5O₂ ---> 4NO + 6H₂O

Therefore,

4 moles of NH₃ reacts with 5 moles of O₂.

i.e,

68 g of NH₃ reacts with 160g of O₂.

Therefore,

9.98 g of NH₃ reacts with :

= 160/68 x 9.98

= 23.4 g of O₂ (up to 3 significant figure)

calculate the volume that will be occupied by 350 ml of oxygen measured at 720 mm hg, when the pressure changed to 630 mm hg

likoan [24]

Answer:

406.45mL

Explanation:

The following data were obtained from the question:

V1 = 350mL

P1 = 720mmHg

P2 = 630mmHg

V2 =?

The new volume can be obtain as follows:

P1V1 = P2V2

720 x 350 = 620 x v2

Divide both side by 620

V2 = (720 x 350) /620

V2 = 406.45mL

The new volume of the gas is 406.45mL

Roman55 [17]

Answer:

The answer is

Explanation:

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

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

From the question

mass = 250 g

volume = 46 mL

The density is

$density = \frac{250}{46} \\ = 5.4347826...$

We have the final answer as

Hope this helps you
