Achemist measures the amount of hydrogen gas produced during an experiment. she finds that 926. g of hydrogen gas is produced. calculate the number of moles of hydrogen gas produced.

Number of moles of hydrogen gas produced is 463.

Explanation:

Mass of hydrogen gas measured by chemist = 926 g

Molar mass of hydrogen gas = 2 g/mol

Moles of hydrogen gas:

Number of moles of hydrogen gas produced is 463.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

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
