A sulfuric acid solution containing 571.3 g of h2so4 per liter of aqueous solution has a density of 1.329 g/cm3. Part a calculat

loris [4]

Mass percentage of a solution is the amount of solute present in 100 g of the solution.

Given data:

Mass of solute H2SO4 = 571.3 g

Volume of the solution = 1 lit = 1000 ml

Density of solution = 1.329 g/cm3 = 1.329 g/ml

Calculations:

Mass of the given volume of solution = 1.329 g * 1000 ml/1 ml = 1329 g

Therefore we have:

571.3 g of H2SO4 in 1329 g of the solution

Hence, the amount of H2SO4 in 100 g of solution= 571.3 *100/1329 = 42.987

Mass percentage of H2SO4 (%w/w) is 42.99 %

What is the mass of 5.07 mol N2?<br><br> (Answer)grams (3 SF)

Nata [24]

Answer:

Mass, m = 141.96 kg

Explanation:

Given that,

Moles = 5.07

Molar mass of N₂ = 28 g/mol

We need to find the mass of 5.07 mol N₂.

We know that,

No of moles is equal to mass divided by molar mass i.e.

$n=\dfrac{m}{M}$

Where

m is mass of 5.07 mol of N₂

So,

$m=n\times M\\\\m=5.07\times 28\\\\m=141.96\ kg$

So, the required mass of 5.07 mol N₂ is 141.96 kg.
