Answer:
molar mass (molar weight)
Explanation:
Answer:
2.35 x 10²⁰ atoms Ga
Explanation:
After converting from mg to g, use the molar mass as the unit converter to convert to moles. Then using Avogadro's number, 6.022 x 10²³ convert from moles to atoms of Ga.
Then round to 3 significant figures = 2.35 x 10²⁰ atoms Ga.
Given that,
The concentration of
TRIS = 0.30 M
The concentration of
TRIS+ = 0.60 M
Kb = 1.2 x 10^-6
pKb = -log Kb = - log
(1.2 x 10^-6) = 5.920
Now, by using the
Hendersonn equation,
pH = pKa + log
TRIS+/TRIS = 5.920 + log (0.60/0.30) = 6.221
<span>pOH=14-pH=14-6.221 =
7.779</span>
2.5 km is the distance you can travel if a car gets 14 kilometers per liter and have 35 liters of gas.
Total distance traveled in 1 liter = 14 km
Total gas in the car = 35 liters
We have to find how much distance can be covered in in35 liters of gas.
Distance is the length of the path traveled between two points. It is the total movement of an object in a direction. It measures length.
Distance = 35/14
Or, distance = 2.5 km
Therefore, the total distance that can be covered by a car in 35 liters of gas is 2.5 km.
