The density is defined as mass of a substance per unit of its volume

It can be expressed in different units like g/L  g/m3  Kg/dm3 etc

We are given that

mass of substance = 27.3 grams

volume of substance = 7 cm^3

the density = Mass of substance / volume of substance

density = 27.3g / 7 cm^3  = 3.9 g /cm^3

density = mass/volume=27.3/7=3.9

Is gas occupies 733 cm at 10.9 at what temp will it occupy 950 cm
alexgriva [62]

Temperature of gas at volume of 950 cm³ is 368.14K or 94.99⁰c.

  • Volume is the amount of space a three-dimensional object takes up, expressed in cubic units.
  • units of volume are mL, liter, cm³ or m³.

Given,

in this question, volume occupied by gas at 10.9⁰c is 733cm³.

we have to find out temperature at which gas occupies volume of 950 cm³.

First, convert temperature from celcius to Kelvin

10.9⁰c = 10.9 + 273.15 = 284.05 K

By equation or Boyle's Law

P1 x V1 / T1 = P2 x V2 / T2

Pressure is constant here

therefore, V1 / T1 = V2 / T2

here, V1 = 733 cm³

T1 = 284.05 K

V2 = 950 cm³

we have to find out T2

So, 733 / 284.05 = 950 / T2

T2 = 284.05 × 950 / 733 = 368.14 K

= 94. 99⁰c

Therefore the temperature of gas at volume of 950 cm³ is 368.14K or 94.99⁰c.
