Answer:
The answer is
<h2>0.5 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of aluminum = 2 g
volume = final volume of water - initial volume of water
volume = 19 - 15 = 4
volume = 4 mL
The density of the metal is
We have the final answer as
<h3>0.5 g/mL</h3>

The answer is hyperbaric medicine.
Hyperbaric medicine is a treatment in which is necessary a chamber with
pressure greater than sea level atmospheric pressure. Is intended to reduce the effects of systemic gas bubbles by reducing their size and lead to their
elimination.
Answer:
intracellular; extracellular
Explanation:
Intracellular fluid compartment is system which includes all the fluid which is enclosed in the cells by the plasma membranes of these cells. It lies in the cells and acts as the principal component of cytoplasm. ICF makes up about 2/3 of total water in human body.
Extracellular fluid is system which surrounds all the cells in body. The fluid has two primary constituents which are - fluid component of blood (known as plasma) and interstitial fluid (IF) which surrounds all the cells except blood. It accounts for other 1/3 of water content of the body.
The correct answer is option B, that is, add 1.46 grams of NaCl to 250 milliliters of H₂O.
First there is a need to find the moles of NaCl in 250 ml of 0.10 M NaCl,
Moles of NaCl = molarity × volume = 0.10 M × (250/1000L) = 0.025 mol
The corresponding mass of NaCl is,
Mass of NaCl = moles × molar mass = 0.025 mol × 58.5 g/mol = 1.46 g
Thus, there is a need to dissolve 1.46 grams of NaCl solid into 50 ml of H₂O and dilute to 250 ml.
