The correct answer would be C.) Length
Answer:
Water in a freezer at -2 degrees Celsius
Answer:
1.23 × 10³ N
Explanation:
Step 1: Given and required data
- Mass of the person (m): 125 kg
- Acceleration due to the gravitational force (g): 9.81 m/s²
Step 2: Calculate the force acting between the Earth and a 125-kg person standing on the surface of the Earth
We will use Newton's second law of motion.
F = m × g
F = 125 kg × 9.81 m/s²
F = 1.23 × 10³ N
Answer:
The osmotic pressure is 10.8 atm
Explanation:
Formula for osmotic pressure is:
π = M . R . T
where M is molarity (mol/L)
R, Universal gas constant (0.082 l.atm/mol.K)
T, T° in K (T°C + 273)
π = M . 0.082 l.atm/mol.K . 318K
Let's calculate the molarity
In 800 mL ____ 60 g
1000 mL _____ 75 g
This is the mass in 1L of solution.
Molar mass glucose = 180.15 g/m
Mass / Molar mass = 75 g/ 180.15 g/m → moles
Moles = 0.416M
π = 0.416 mol/l . 0.082 l.atm/mol.K . 318K
π = 10.8 atm
Answer:
I can't do that but this is the best I can do for you :(
Explanation:
Nitric acid, HNO3(aq), breaks up into ions (a cation and an anion) in a water solution.
