Answer:

See below in bold.

Explanation:

Nitrogen, Hydrogen and Oxygen are the elements present in ammonium nitrate.

The Molar Mass = 2N + 4H + 3 O

= 2*14.007 + 4*1.008 + 3*15.999

= 80.043.

Percentage of Nitrogen = (2 * 14.007) * 100 / 80.043

= 35.00 %.

Percentage of Hydrogen = (4* 1.008) * 100 / 80.043

= 5.04%.

Percentage of Oxygen = (3 * 15.999) * 100 / 80.043

= 59.96 %.

Tanzania [10]

Hello!

Mass =4.2 g

Volume =6 mL

Therefore:

Density = mass / volume

Density = 4.2 / 6

Density = 0.7 g/mL

A sample of gas at 1.10 atm has a volume of 326 mL. What is the new volume if the pressure is changed to 1.90 atm?

Brut [27]

Answer

For this we use ideal gas equation which is:

P1V1 = P2V2

P1 = 1.10 atm

V1 = 326 ml

P2 = 1.90

V2 = ?

By rearranging the ideal gas equation:

V2 = P1V1 ÷ P2

V2 = 1.10 × 326 ÷1.90

V2 = 358.6 ÷ 1.90

V2 = 188.7 ml
