Answer:
23.2L
Explanation:
The following were obtained from the question:
V1 = 22.5L
P1 = 748 mmHg
P2 = 725mmHg
V2 =?
The new volume can be obtained by doing the following:
P1V1 = P2V2
22.5 x 748 = 725 x V2
Divide both side by 725
V2 = (22.4 x 748) /725
V2 = 23.2L
The new volume is 23.2L
Answer is distillation.
the less polar liquid will distill faster at lower temperature compared to the polar liquid
Answer:
A compound can easily be split up into its different elements.
Explanation:
The density increases as the substance cools.
The mass of sulfur in a sample of CaSO4 with a mass of 65.8 g is 15.50g.
<h3>How to calculate mass of an element in a compound?</h3>
According to this question, a 10.4 g sample of CaSO4 is found to contain 3.06 g of Ca and 4.89 g of O.
This means that the mass of sulfur in the 10.4g of CaSO4 is 10.4g - (3.06g + 4.89g) = 10.4g - 7.95g = 2.45g
Next, we calculate the percent ratio of each element in the compound; CaSO4.
- Ca = 3.06g/10.4g × 100 = 29.42%
- S = 2.45g/10.4g × 100 = 23.56%
- O = 4.89g/10.4g × 100 = 47.02%
According to this question, a sample of CaSO4 with a mass of 65.8 g is given. The mass of each element in this compound is as follows:
- Ca = 29.42/100 × 65.8g = 19.36g
- S = 23.56/100 × 65.8g = 15.50g
- O = 47.02/100 × 65.8g = 30.94g
Therefore, the mass of sulfur in a sample of CaSO4 with a mass of 65.8 g is 15.50g.
