How many moles of h2o are equivalent to 97.3 grams of h20

Answer : 5.405 moles of are equivalent to 97.3 grams of

Solution : Given,

Mass of = 97.3 g

Molar mass of = 18 g/mole

Formula used :

or,

Now put all the given values in this formula, we get the moles of

Therefore, 5.405 moles of are equivalent to 97.3 grams of

its first and third is your answer i did the qustion the fourth isnt right

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
