Hello!
We use the amount in grams (mass ratio) based on the composition of the elements, see: (in 100 g solution)
C: 83.7% = 83,7 g
H: 16.3% = 16.3 g
Let us use the above mentioned data (in g) and values will be converted to amount of substance (number of moles) by dividing by molecular mass (g / mol) each of the values, lets see:


We note that the values found above are not integers, so let's divide these values by the smallest of them, so that the proportion is not changed, let's see:


Note: So the ratio in the smallest whole numbers of carbon to hydrogen is 3:7, t<span>hus, the minimum or empirical formula found for the compound will be:

I hope this helps. =)

Explanation:
Charles' Law can be stated as follows: At constant pressure, the volume of a given mass of gas varies proportionally with the value of its absolute temperature.
Answer: D. Pressure.
This. You welcome now can you plz give me thanks and brainly
Answer:
1867.88g
Explanation:
The density of a substance can be calculated by dividing its mass by its volume. That is;
Density = mass/volume
In this question, the density of water is given as is 0.9870 g/mL, volume of water held by the container is 64 fluid ounces.
The unit, however, must be the same in order to work.
Since; 29.57 mL = 1 fluid ounce
64 fluid ounces will be 64 × 29.57 mL
= 1892.48 mL
Using the formula above, the mass (m)= density (p) × volume (v)
Mass = 1892.48mL × 0.9870 g/mL
Mass= 1867.8776
Mass = 1867.88g
