Answer:
1. answer is subcutaneous tissue 2. answer is spleen
Explanation:
The subcutis is also known as the hypodermis or subcutaneous layer, and functions as both an insulator, conserving the body's heat, and as a shock-absorber, protecting the inner organs.
Excretory Organs. Organs of excretion include the skin, liver, large intestine, lungs, and kidneys. Together, these organs make up the excretory system.
Answer:
0.534
Explanation:
Mole fraction can be calculated using the formula:
Mole fraction = number of moles of solute ÷ number of moles of solvent and solute (solution).
In this question, solute is dimethyl ether while the solvent is methanol.
Mole (n) = mass (M) ÷ molar mass (MM)
Mole of solute (dimethyl ether) = 148.5 ÷ 46.07
= 3.22moles.
Mole of solvent (methanol) = 90 ÷ 32.04
= 2.81moles.
Total moles of solute and solvent = 3.22 + 2.81 = 6.03moles.
Mole fraction of dimethyl ether = number of moles of dimethyl ether ÷ number of moles of solution (dimethyl ether + methanol)
Mole fraction = 3.22/6.03
= 0.534
Hello!
Reading the worksheet shows you how to find the concentration of liquid water in a substance, but when converting a decimal to a percentage, remember that ALL percentages are out of 100, so, we multiply the decimal by 100 to convert it into a percentage.
Liquid A: total amount: 10 millimeters & amount of water: 7 millimeters
7/10 = 0.7 × 100 = 70%
Liquid B: total amount: 100 millimeters & amount of water: 92 millimeters
92/100 = 0.92 × 100 = 92%
Liquid C: total amount: 15 millimeters & amount of water: 13 millimeters
13/15 = 0.867 × 100 = 86.7%
Liquid D: total amount: 28 millimeters & amount of water: 22 millimeters
22/28 = 0.786 × 100 = 78.6%
<u>Final answers</u>:
- Liquid A: 70%
- Liquid B: 92%
- Liquid C: 86.7%
- Liquid D: 78.6%
