Answer:
0.17×10⁻³ mol
Mass = 0.00476 g
Explanation:
Given data:
Number of molecules of N₂ = 1 ×10²⁰ molecules
Number of moles of N₂ = ?
Mass in gram of N₂ = ?
Solution:
1 mole of any substance contain 6.022×10²³ molecules
1 ×10²⁰ molecules× 1 mol /6.022×10²³ molecules
0.17×10⁻³ mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.17×10⁻³ mol × 28 g/mol
Mass = 4.76×10⁻³ g
Mass = 0.00476 g
Analytical chemistry studies and uses instruments and methods used to separate, identify, and quantify matter
Answer:
3.25 moles of sodium chloride to grams: 189.3545 grams
Explanation:
1 moles NaCl = 58.44277 gram
Answer:
Shear stress
Explanation:
Shear stress occurs in what we call transform boundaries. Transform boundaries happen when two tectonic plates slide against each other.
There are 3 main types of stress and shear stress is one of them.
Additional information ahead, continue reading if you'd like to know more.
Compression stress occurs when two tectonic plates are convergin g (at convergent boundaries).
Tension stress occurs when two tectonic plates are diverging, or when they are moving apart, (at divergent boundaries).
