g If 480µg of Nitrous Oxide escapes into a closed room 10 ft. x 8 ft. x 12 ft., how many Mg/M3 is this? 1M3 = 35.315 ft.3; 1000 µg = 1 Mg

if you're asking what comes out, it's steam.

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

1 is the answer to this problem
