I think it’s B because I just know
Answer:
2.67 M
Explanation:
Molarity, which is the molar concentration of a substance, can be calculated using the formula;
M = n/V
Where;
M = molarity (M)
n = number of moles (mol)
V = volume (Litres)
Based on the provided information in this question, mass of lithium sulfate (Li2SO4) = 734g, volume = 2.5L
Using mole = mass/molar mass
Molar mass of Li2SO4 = 7(2) + 32 + 16(4)
= 14 + 32 + 64
= 110g/mol
Mole = 734/110
Mole (n) = 6.67moles
Molarity = n/V
Molarity = 6.67/2.5
Molarity = 2.668
Molarity of Li2SO4 in the solution is 2.67 M
Answer:
B.) Adhesion
Explanation:
A.) is incorrect. Viscosity is a measure of internal friction that affects the fluidity of a liquid.
B.) is correct. Adhesion is the ability of water to stick to other substances (which are not water).
C.) is incorrect. Surface tension is the tension created by the bonds of the surface particles.
D.) is incorrect. Density is a ratio that compares mass to volume.
Answer:
Two similar atoms or different atoms
Explanation:
A molecule is made up of at least two similar atoms or different atoms.
A molecule is the smallest particle of a substance capable of independent existence.
- Monoatomic molecule is made up of one atom
- Diatomic molecule is made up of two atoms bounded together.
- Polyatomic molecule are made up of more than two molecules bounded together.
