The mass of a present which has a density of 2.15 kg/L and volume of 3650 mL is 7.74 kg.
<h3>How do we calculate mass?</h3>
Mass of any substance will be calculate by using the density and volume by using the below equation as:
Density = Mass / Volume
Given that,
Density of Christmas present = 2.15 kg/L
Volume of present = 3,650 mL = 3.6L
On putting values, we get
Mass = (2.15)(3.6) = 7.74
Hence required mass of Christmas present is 7.74 kg.

This problem is providing information about the moles of ammonia that are consumed in excess copper(II) oxide and the produced moles of nitrogen, copper and water are required.
<h3>Chemical equation:</h3>
At first instance, we must write the balanced chemical reaction that takes place when the aforementioned reactants are reacted, in agreement to the law of conservation of mass:
<h3>Mole ratios:</h3>
Next, since 6.5 moles of ammonia, NH3, is given, it turns out possible for us to apply the following mole ratios in order to calculate the required moles of each product:
