A sample of nitrogen gas had a volume of 500. mL, a pressure in its closed container of 740 torr, and a temperature of 25 °C. What was the new volume of the gas when the temperature was changed to 50 °C and the new pressure was 760 torr, if the amount of gas does not change?

The amount of final volume when mass of the system is constant =

0.526 L

Explanation:

Given data

= 500 mL = 0.5 L

= 740 torr

= 25 ° c = 298 K

= 50 ° c = 323 K

= 760 torr

From ideal gas equation we get

0.526 L =  526 ml

This is the amount of final volume when mass of the system is constant.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
