Answer:
Explanation:
Attach is the net ionic equation
Taking into account the definition of density, the mass of a substance with a volume of 150 cm³ and a density of 1.5
is 225 grams.
<h3>What is density</h3>
Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
<h3>Mass of the substance in this case</h3>
In this case, you know that:
- Density= 1.5

- Volume= 150 cm³
Replacing in the definition of density:

Solving:
mass= 1.5
×150 cm³
<u><em>mass= 225 g</em></u>
In summary, the mass of a substance with a volume of 150 cm³ and a density of 1.5
is 225 grams.

Answer:
speed
Explanation:
Speed is the rate at which something moves. The speed of light is faster than the speed of sound.
Since we are already given the balanced equation:
→ 
We can derive the molar ratios as: 1:2:1:1
That being said, we are given 0.172 moles of bromine (
), so it has a ratio of 1:1 with sodium bromide (
).
So we can take from that ratio, that when 0.172 moles of bromine are used, we are, in turn, going to get 0.172 moles of sodium bromide produced.
