The mass of a substance per unit volume is the substance's density.
D = m/v.
Answer:
The answer to your question is: 101.2 g of CO2
Explanation:
C = 27.6 g
O₂ = 86.5 g remained 12.9 g
O₂ that reacted = 86.5 - 12.9 = 73.6 g
C + O₂ ⇒ CO₂ The equation is balanced
27.6 73.6 ?
MW 12 32 44
Rule of three
12 g of C------------------ 44 g CO2
27.6 g C ------------------ x
x = 27.6(44)/12 = 101.2 g of CO2
32 g of O2 --------------- 44 g of CO2
73.6 g of O2 ------------ x
x = 73.6(44)/32 = 101.2 g of CO2
Answer:

Explanation:
Hello there!
In this case, according to the given information, it turns out firstly necessary for us to set the equation for the calculation of density and mass divided by volume:

Thus, we can find the mass of the unknown by subtracting the total mass of the liquid to the mass of the flask and the liquid:

So that we are now able to calculate the density in g/mL first:

Now, we proceed to the conversion to lb/in³ by using the following setup:

2NH₃(g) + CO₂(g) → CO(NH₂)₂(s) + H₂O(l)
is the balanced equation for the synthesis of urea.
Answer:
repetition
Explanation:
Taking an average of 16 height measurements is an example of repetition. Repetition involves making and taking repeated measurements in an experiment.
The goal is to achieve a highly accurate and precise data from the experiment.
- Replication involves duplicating another experiment and testing to see how valid they are.
- Since Veronica's experiment is a brand new one, it's hypothesis has not been tested or replicated in any way.
- Therefore, it is not a replication.
- But she is repeating the experiment to obtain different values.
