Properties of Water Essential to Life</u></h2>
<u></u>
- Water is known to be the universal solvent because of <u>its ability to dissolve more particles</u> than any other liquid.
- Cohesion is the <u>property of water to attract other molecules</u>. This helps in making solutions that are essential for most life to propagate.

Answer: A mole is a unit of measurement.
Explanation:
moles= mass/molar mass
for example moles=1000g/342.296 g/mol
moles=2.921 mol
Answer:
Magnesium chloride/Molar mass
95.211 g/mol
Explanation:
D is the answer sorry if wrong
Answer: The mass of 45.0 L of at 87.0° C and 750 mm Hg is 56.605 g.
Explanation:
Given: Volume = 45.0 L
Temperature = = (87.0 + 273) K = 360 K
Pressure = 750 mm Hg (1 mm Hg = 0.00131579 atm) = 0.98 atm
Formula used to calculate moles is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
Moles is the mass of a substance divided by its molar mass. So, mass of (molar mass = 37.99 g/mol) is calculated as follows.
Thus, we can conclude that the mass of 45.0 L of at 87.0° C and 750 mm Hg is 56.605 g.
