Answer:
This part require data such as Avogadro's number and the molar mass of water. But first, let's find the mass of water in the specified volume by making use of the density formula:
Density = mass/volume
1 g/mL = Mass/70 mL
Mass = 70 g
Each water contains 18 grams per mole, and each mole contains 6.022×10²³ molecules of water. Thus,
70 g * 1mole/18 g * 6.022×10²³ molecules/mole = 2.342×10²⁴ molecules of water
Explanation:
165 Pounds (lbs) = 74.84 Kilograms (kg)
1 lbs = 0.453592 kg 1 kg = 2.204623 lbs
Answer:
2.00x10⁵L
Explanation:
<em>...That contains 125g of mercury(I) chloride...</em>
<em />
The molarity, M, of a solution represents the moles of solute (Mercury(I) chloride), per liter of solution.
To solve this question, we need to determine the moles of mercury(I) chloride present in 125g. Then, with molarity, we can find the volume of the solution:
<em>Moles Mercury(I) chloride -Molar mass: 271.52g/mol-:</em>
125g * (1mol / 271.52g) = 0.460 moles
<em>Volume:</em>
0.460 moles * (1L / 2.3x10⁻⁶mol) =
<h3>2.00x10⁵L</h3>
