Molar mass NF₂ => 52.00 g/mol
Atomic mass N => 14 a.m.u
% N = ( Atomic mass N / molar mass NF₂ ) x 100
( 14 / 52 ) x 100 = 26.92%
hope this helps!
Hey i dont have an answer but i need the points for finals today. Thank you
Answer:
2.73%
Explanation:
Molarity of NaOH = 0.75 M
Density of solution = 1.1 g/mL
Mass percent of NaOH = ?
Solution:
Number of moles of NaOH = 0.75 mol from 0.75 mol/L
Mass of NaOH = number of moles × molar mass
Mass of NaOH = 0.75 mol × 40 g/mol
Mass of NaOH = 30 g
Mass of solution:
d = m/v
1.1 g/ mL = m/ 1000 mL
m = 1100 g
Percentage of NaOH:
% NaOH = mass of solute / mass of solution × 100
% NaOH = 30 g/ 1100 g × 100
% NaOH = 2.73%
A substance above its critical pressure is <span>supercritical.
I hope this helps you! Good luck :)</span>
I believe the answer is diamond. Hope this helps!
