First, need to know the formula of Molarity.
moles of solute
Molarity = ---------------------------
liters of solution
Given
2.0 liter of solution
58 grams of NaCl
Base of my research the moles of 58 grams of NaCl is 0.750 moles
Solution
0.750 moles
Molarity = ----------------------- = 0.375
2.0 L
The molarity of this solution is 0.375
Answer:
50kg
Explanation:
Using the formula for potential energy, which is the amount of energy due to position;
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (metres)
According to the information provided in this question, m = ?, P.E = 2500J, h = 5m
Using P.E = m × g × h
m = P.E/gh
m = 2500/(5 × 10)
m = 2500/50
m = 50kg
The mass of the man is 50kg.
A.Genus And Species. FOR EXAMPLE HUMAN, Genus-homo And Species-sapiens Which For Homo Sapiens.
Use Charle's Law because we are dealing with volume and temperature.
v₁= 3017.0 ml
t₂ = 0
v₂= ???
t₂= 273°C
Change all mL's to L because the question says "What is the volume (L)...".
3017.0 mL = 3.017 L
Change the temperature into Kelvins: <em>Kelvin = Celsius + 273.15</em>
0°C = 273.15 K
273°C = 546.15 K
Now you can plug it in the formula:
Then, do cross multiplication.
(3.017) (546.15) = (273.15) v₂
1,647.73 = (273.15 K) v₂
<em> Divide 273.15 on both sides</em>
<em>6.0296 L= V₂</em>
