What pressure will be produced when 2.0 moles of N2 gas is heated to 68oC in a container that holds 1.25 of gas?
Stella [2.4K]

The pressure of the nitrogen gas produced is determined as 44.77 atm.

<h3>What is the pressure of the Nitrogen gas?</h3>

The pressure of the nitrogen gas is determined from ideal gas equation, as shown below;

PV = nRT

P = nRT/V

where;

  • n is number of moles = 2 moles
  • R is ideal gas constant = 0.08205 L.atm/mol.K
  • T is temperature = 68⁰C = 68 + 273 = 341 K
  • V is volume = 1.25 L

P = (2 x 0.08205 x 341)/(1.25)

P = 44.77 atm.

What is the density of marble that has a mass of 4.3 g and a volume of 2.7 cm?
KiRa [710]

Explanation:

density(d) = mass(m) × volume(v)

given:

mass = 4.3 g = 0.0043 Kg

volume = 2.7 cm³ = 0.027 m³

= 0.0043 Kg / 0.0027 m³

= 0.15 Kg/m³
