The volume of N₂ at STP=56 L

<h3>Further explanation</h3>

Given

2.5 moles of N₂

Required

The volume of the gas

Solution

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, the volume per mole of gas or the molar volume-Vm is 22.4 liters/mol.

So for 2.5 moles gas :

\tt 2.5\times 22.4=56~L

Alex Ar [27]
<span>The amount of dissolved salt in the liquid sample is measured and reported as salinity. The salinity is usually measured in parts per thousand (ppt). The salinity of ocean averages 35 ppt while that of the river averages 0.5 ppt or less. In other terms, the word salinity is the saltiness. </span>

Your apple juice has a molarity of 3.4 M and a volume of 0.895 litres. What does a student have to do to decrease the molarity t
Jlenok [28]

Answer:

4.285 L of water must be added.

Explanation:

Hello there!

In this case, for this dilution-like problems, we need to figure out the final volume of the resulting solution so that we would be able to obtain the correct volume of diluent (water) to be added. In such a way, we can obtain the final volume, V2, as shown below:

M_1V_1=M_2V_2\\\\V_2=\frac{M_1V_1}{M_2}

Thus, by plugging in the initial molarity, initial volume and final molarity (0.587 M) we obtain:

V_2=\frac{3.4M*0.895 L}{0.587M}\\\\V_2=5.18L

It means we need to add:

V_{H_2O} ^{added}=5.18L-0.895L=4.285L

Of diluent water.

Regards!
