Molar mass H₃PO₄ = 98.0 g/mol
1 mole ----- 98.0 g
? mole ------ 30.0 g
moles = 30.0 * 1 / 98.0
= 0.306 moles
hope this helps!
First find the number of moles of sulfur using dimensional analysis with avogadro’s number as the conversion factor. 4.2*10^24 atoms * (1 mol/6.022*10^23 atoms) = 7.0 mol sulfur. The molar mass of sulfur is 32.06 g/mol, which is found on the periodic table as sulfur’s (S) atomic weight. Use dimensional analysis again with the molar mass of sulfur as the conversion factor. 7.0 mol * 32.06 g/mol = 224.42 g sulfur. Since the problems gives us two significant figures, round the mass of sulfur to 220 grams, or 2.2 * 10^2 g.
Answer:
I think that you want no, of moles
Explanation:
no, of mole of this amount= 15/44 = 0.341 mole
Answer:
it's the electron cloud model
Answer:
Aluminum (blended with small quantities of other metals) is used on most types of aircraft because it is lightweight and strong. Aluminum alloys don't corrode as readily as steel. It has also been used for the skin of some high-speed airplanes, because it holds its strength at higher temperatures better than aluminum.
HOPE THIS HELPED!!!!!!!!!XDDD
