Explanation: molar mass of N2=28

Volume occupied at stp=22.4 so 28/22.4=1.25 so mass nitrogen will be 56 multiply 1.25 =70g

Answer: 2.68 grams

Explanation:

According to avogadro's law, 1 mole of the substance occupies 22.4 liters at STP and contains avogadro's number 6.023\times 10^{23} of particles and weighs equal to its molecular mass.

1 mole of N_2 weighs 28 grams.

Also 1 mole of N_2 occupies 22.4 Liters.

Thus 22.4 L N_2 weigh = 28 grams

2.15 L of N_2 weigh =\frac{28}{22.4}\times 2.15=2.68g

Thus the mass of nitrogen gas is 2.68 grams.

Is the dissolution of borax in water a temperature dependent reaction or is it spontaneous at all temperatures at which water is
enot [183]

The dissolution of borax in water is a temperature dependent reaction. With the higher temperature, the salt dissolve quickly.

<h3>What is borax?</h3>

Borax is the hydrate salt of boric acid. It is white and widely used in cleaning and in laundry  detergent.

Borax is a salt that will dissolve in water at almost any temperature, with the exception of steam and ice.

However, as with any salt, the higher the temperature, the faster the salt dissolves, so speed is dependent on temperature. It will dissolve in cold water, but it will take longer.

Thus, the dissolution of borax in water is a temperature dependent reaction.
