How many moles of h2o are equivalent to 97.3 grams of h20
g100num [7]

Answer : 5.405 moles of H_2O are equivalent to 97.3 grams of H_2O

Solution : Given,

Mass of H_2O = 97.3 g

Molar mass of H_2O = 18 g/mole

Formula used :

\text{ Number of moles}=\frac{\text{ Given mass}}{\text{ Molar mass}}

or,

\text{ Number of moles of }H_2O=\frac{\text{ Given mass of }H_2O}{\text{ Molar mass of }H_2O}

Now put all the given values in this formula, we get the moles of H_2O

\text{ Number of moles of }H_2O=\frac{97.3g}{18g/mole}=5.405moles

Therefore, 5.405 moles of H_2O are equivalent to 97.3 grams of H_2O

A sample of seawater has 0.075 g of sodium chloride per mL of solution. How many moles of sodium chloride are there per liter of
amm1812

Answer:

1.28 mol

Explanation:

mole = mass/molar mass

n = v/v/cm³

mass = 0. 075g

v = 1dm³ =1000cm³

n= m/MV=0.075/58.44(1000)

n =1.28 mol
