Law Incorporation [45]

Aspartame (C₁₄H₁₈N₂O₅) is a solid used as an artificial sweetener. its combustion produces carbon dioxide gas, liquid water, and nitrogen gas

C₁₄H₁₈N₂O₅ + 16O₂-----> 14CO₂ + 9H₂O + N₂.

As it can be seen from the equation, that the coefficient of nitrogen gas in the balanced equation for the reaction is 1.

So the answer here is 1 only that is coefficient of nitrogen gas in the balanced equation for the reaction is 1.

A student measures the mass of an 8 cm block of brown sugar to be 12.9 g. What is the density of
horrorfan [7]

Answer:

0.0025g/cm³

Explanation:

Given parameters:

Mass of the brown sugar = 12.9g

dimension of the sugar = 8cm

unknown:

density of the sugar = ?

Solution

Density is defined as the mass per unit volume of a substance. The expression is given below:

      Density = \frac{mass}{volume}

We know the mass of the substance but the volume is unknown:

Volume of the brown sugar = l x bx h = 8x8x8 = 512cm³

Density of the brown sugar = \frac{12.9}{512} = 0.0025g/cm³
