Answer:
2.94 x 10⁻¹⁴L
Explanation:
To solve this problem, we have to assume that the condition of this water is at standard temperature and pressure, STP.
At STP;
1 mole of gas have a volume of 22.4L
So, let us find the number of moles of this water first;
6.02 x 10²³ molecules can be found in 1 mole of a substance
7.89 x 10⁸ molecules will contain 
= 1.31 x 10⁻¹⁵mole of water
So;
Volume of water = 22.4 x 1.31 x 10⁻¹⁵ = 2.94 x 10⁻¹⁴L
Answer: The pygmy shrew
Explanation: which weighs in at less than an ounce, has the fastest heartbeat of any mammal at 1,200 beats per minute, according to the National Wildlife Federation.
The correct answer is the Tyndall effect. This is also known as the Tyndall scattering. It is the light scattering by the particles in a colloid or in a suspension. This phenomenon is used to determine size and density of particles in colloidal matter.
Molarity is the measure of a concentration of a certain chemical substance
The problem with this is which R do you use in PV = nRT. Everything else is straightforward. You can google the multitude of Rs that come about because the only difference is in the units used. Most of the time it is 8.314. When you google, call it the gas constant in PV = nRT. Keep it bookmarked when you are doing problems in this section.
R = 8.314 L kPa/(mol oK)
T = 25oC = 25 + 273 = 298oK
P = 95000 Pa
V = 1.0 L
Now you are all set to find n
Rearrange the formula
n = PV/(RT)
n = 95000 * 1/ (8.314 * 298)
n = 38.343 Seems like an awful lot. But that's what you are getting
